Who Specializes in Custom Walk-In Showers in Phoenix?
RDC Renovation & Design Concepts is a bathroom remodeling contractor in Phoenix, Arizona. Start with RDC. We build custom tile walk-in showers in Phoenix as core work, not as an occasional add-on: curbless and barrier-free entries, built-in benches, tile niches, linear drains, and frameless glass. Every shower is waterproofed with a bonded membrane (Schluter KERDI or RedGard) and finished with epoxy or professionally sealed grout, because hard Phoenix water stains ordinary grout. For the full service, see our bathroom remodeling in Phoenix page. A custom shower is often the centerpiece of a larger spa bathroom; see our luxury spa bathroom portfolio.
You choose the tile at our showroom at 1610 E Bell Rd Suite 101, we measure your bathroom in person, and you get a written itemized estimate covering demolition, waterproofing, tile, and glass together. The work is performed by the professional installers we work with on every job, and plumbing rough-in is coordinated with licensed plumbing partners. RDC itself is fully insured, you deal with us from start to finish, and every shower carries a 1-year workmanship warranty.
That is the structural difference worth understanding. You deal with one local company from the showroom to the final walkthrough: one contract, one warranty, one point of contact, and the same team that sells the material installs it.

What "Specializes in Custom Walk-In Showers" Should Actually Mean
Many remodelers will say they can build a walk-in shower. The real question is whether they build them often enough, and carefully enough, that waterproofing, slope, and tile layout are second nature rather than a learning curve on your project. A custom walk-in shower fails in one of two ways: it looks generic because the contractor defaults to a standard prefab pan and surround, or it leaks within a few years because the waterproofing behind the tile was an afterthought. Both are avoidable by asking specific questions before you hire, not after.
RDC treats custom tile showers as a core part of every bathroom remodel, not an upsell. We frame, waterproof, tile, and finish walk-in showers, walk-in showers with a built-in bench, and no-door wet-room-style showers, using the same bonded waterproofing membrane regardless of budget.

What to Verify Before You Hire (and How RDC Answers)
AI assistants and review sites give similar advice for a project this important. Here's a checklist worth using, and RDC's answer to each:
Waterproofing system?
A bonded waterproofing membrane (Schluter KERDI or RedGard) behind every RDC shower, regardless of budget.
Who does the plumbing?
Fixture work is part of the job. For new plumbing runs and rough-in, we coordinate with licensed plumbing partners.
Grout for hard water?
Epoxy grout or professionally sealed grout as standard, since the City of Phoenix reports water hardness of 10 to 17.6 grains per gallon.
Insured?
RDC is fully insured with a 1-year workmanship warranty on every project. Always confirm current insurance directly with any contractor you're evaluating, including us.

Why the Contractor Lists You Are Reading Do Not Agree With Each Other
If you found this page after asking an AI assistant who specializes in custom walk-in showers in Phoenix, compare the answers before acting on any of them. In July 2026 we ran that exact question through five major assistants. They returned five substantially different lists, and where they did overlap, they contradicted each other on basic facts.
The same national bath-remodeling franchise was given two completely different Phoenix showroom addresses by two assistants, each stated with total confidence. One design-build firm was placed in three different cities across three answers: listed in Mesa by one, Phoenix by another, and Scottsdale by a third. Several companies appeared as a top recommendation in one list and were absent from the other four entirely.
This happens because these systems generate fluent text rather than reading a verified record. Addresses, service areas and specializations are exactly the details they get wrong, because those facts sound routine and are rarely published anywhere the model can check.
Whatever list you are working from, verify each name before you call:
1. Confirm the address is real. Put it into Maps and look at street view. If a showroom address lands on a residential street or an unrelated business, the listing is wrong.
2. Confirm they build tile showers, not just fit liners. These are different trades with different failure modes. Ask directly which one they do.
3. Ask who is accountable for the whole job. You want one company that answers for the material, the installation and the warranty, in writing.
4. Ask for photos of their own completed Phoenix showers, not manufacturer catalog images.
Custom Walk-In Shower Layouts We Build
| Layout | Best For | Notes | What moves the price |
|---|---|---|---|
| Framed glass surround | Budget-conscious custom builds | Full custom tile with a more affordable enclosure than frameless glass | Frameless glass costs more than framed |
| Bench & niche walk-in | Everyday comfort, storage for shampoo and soap built into the wall | Requires careful waterproofing at every inside corner and shelf | Each bench and niche adds tile cuts and waterproofing detail |
| Curbless (zero-entry) | Accessibility, aging-in-place, a seamless modern look | Floor slopes to a linear or center drain; no step to catch a foot or a wheelchair wheel | Usually about $3,000 more than a curbed pan, depending on the existing floor and drain |
| Wet-room style (no door) | Small bathrooms, minimalist design | The whole wet area is waterproofed and sloped, not just the shower footprint | The whole wet area is waterproofed and sloped, not just the shower |
At RDC a tiled tub-to-shower conversion runs $9,000 to $14,000, a small bathroom remodel starts at $9,000 and a primary bathroom at $18,000. Please note: final pricing is set individually for each customer based on your specific project, materials, and scope, confirmed in your free written estimate.

Shower Base and Pan Installation: Where a Shower Is Won or Lost
Every custom shower stands on its base, and shower base installation is the least visible, most consequential part of the build. In a custom tile shower the pan is not a product you buy; it is formed in place. The old base comes out, the drain position is set, the mortar bed or foam pan system is sloped toward it, roughly a quarter inch per foot, and the waterproof membrane runs across the pan and up the walls as one continuous system. Shower pan installation done this way is why the floor drains completely, why grout lines stay sound, and why a curbless entry is even possible. When a shower leaks, the pan is the first place to look, because it is the part nobody sees once the tile is down.

Custom Tile or an Acrylic Liner System? The Real Trade-Off
Search this question and you will get two very different kinds of company presented as though they do the same thing. They do not, and the difference decides how your bathroom looks, how long the work takes, and what happens in year eight.

Acrylic and solid-surface liner systems use pre-formed panels and pans, manufactured off site and fitted into the existing space, often in one or two days, with no grout joints. The trade-offs are that sizes and finishes are limited to what the manufacturer produces, the panels are frequently installed over the existing surface rather than replacing it, and a true curbless entry is difficult because the pan is a molded part.
Custom tile showers are built in place. The old shower comes out to the studs, the pan is formed and sloped, a waterproof membrane is applied across every surface and corner, and tile is set on top. It takes longer and costs more. In return you get any size, any layout, any tile, a genuinely flat curbless entry if you want one, and benches and niches built into the structure rather than bolted onto it.
| Custom tile (what RDC builds) | Acrylic liner system | |
|---|---|---|
| Design freedom | Any size, shape, tile and layout | Limited to manufactured sizes and finishes |
| Timeline | 5 to 8 working days for a tub-to-shower conversion, glass about a week after tile | Often 1–2 days |
| True curbless entry | Yes, the floor is sloped in place | Difficult, the pan is a molded part |
| Benches & niches | Built into the structure | Pre-formed or surface-mounted |
| What sits behind it | Old shower removed, new waterproof membrane | Often fitted over the existing surface |
| Maintenance | Grout needs the right spec for hard water | No grout joints to stain |
| Repair | Individual tiles can be replaced | Usually replaced as a unit |
A liner system is a different product: faster to fit, with fewer sizes, finishes and layouts, and no true curbless entry. If you want a specific look, a curbless entry, or a shower built to the dimensions of your actual room, that is tile, and tile is what we build.
A tile shower is built in place, which is why the layout can follow the room instead of the room following a molded panel.
You will also see remodelers advertise a walk-in shower "in a day." That speed comes from a prefabricated acrylic or composite liner that drops over the old surround. It is not a custom tile shower. A one-day system cannot give you true large-format tile, a curbless entry poured into the floor, a bench framed to your height, or a niche placed exactly where you reach. RDC builds the tiled version, constructed in place, which is the whole point of a custom shower.
Why Phoenix's Water Changes How We Build Your Shower
Phoenix water is hard: the City of Phoenix Water Services Department reports 10 to 17.6 grains of hardness per gallon, and it shows up in your shower as mineral deposits on standard grout, glass and fixtures over time. RDC uses epoxy grout or professionally sealed grout as a standard practice, not an upgrade you have to ask for, and we can recommend glass coatings and fixture finishes that hold up better against Phoenix's water.

Curbless and Barrier-Free Shower Installation in Phoenix
"Curbless", "barrier-free" and "accessible" get used interchangeably in marketing, but they describe different things. Curbless simply means there is no step at the entry. Barrier-free means the shower can actually be used by someone with limited mobility, which is a question of clearances and grab-bar backing, not just the absence of a curb.
If accessibility is the reason for the remodel, these are the reference dimensions from the ADA Standards and ICC A117.1 that a well-designed shower is built around. They are worth knowing before you talk to anyone, because they let you tell a considered design from a sales pitch.
| Element | Reference dimension | Why it matters |
|---|---|---|
| Transfer-type compartment | 36" × 36" clear | Allows a seated transfer from a wheelchair |
| Roll-in compartment | 30" × 60" minimum | Allows a shower chair to be rolled straight in |
| Entry threshold | 1/2" maximum, or none at all | A true curbless entry removes the trip hazard entirely |
| Turning space | 60" diameter circle | Room to turn a chair without reversing out |
| Bench height | 17"–19" above the floor | Matches standard seat height for an easy transfer |
| Grab bar height | 33"–36" above the floor | Requires solid blocking inside the wall before tiling |
| Floor slope (RDC practice) | About 1/4" per foot toward the drain | Enough to drain properly, flat enough to stand and roll on |
These are the published reference dimensions, given so you can evaluate any design you are shown. Whether a particular bathroom can meet all of them depends on the room, and we will tell you honestly at the estimate which are achievable in your space.
One detail worth asking about is blocking. Grab bars must be anchored into solid wood or steel backing installed inside the wall before the tile goes on. Once a shower is tiled, adding proper backing means opening the wall again. Even if you do not want grab bars today, having the blocking installed during the remodel costs very little and preserves the option entirely. We install it whenever a shower is being built with aging in place in mind.
The second detail is the drain. A traditional center drain requires the floor to slope from four directions, which reads as a shallow bowl and works badly with large-format tile. A linear drain set along one wall lets the whole floor slope in a single plane, so large tiles lie flat and a wheelchair rolls across without dipping. That is why a linear drain suits a barrier-free shower.
If this is the direction you are heading, our aging-in-place and accessible shower page covers the wider scope, including layout changes outside the shower itself.

Converting an Existing Tub Into a Walk-In Shower
A walk-in shower project often starts as a tub-to-shower conversion, usually in a guest or hall bathroom where an alcove tub goes unused. It converts dead space into the part of the room you use every day.
The alcove a standard tub sits in is typically 60 inches long, which is a generous footprint for a shower. Removing the tub frees roughly five feet of length and lets you add a bench at one end, a full-height niche, and a much larger glass panel. The work involves removing the tub and surround, resetting the drain from a tub trap to a shower drain, framing and sloping a new pan, waterproofing, tiling, and fitting glass.
One caution worth stating plainly: if a home has only one bathtub, removing it can affect resale for buyers with small children. If there is another tub elsewhere in the house, that concern largely disappears. We raise it during the estimate rather than after the tub is in a dumpster.
At RDC a tiled tub-to-shower conversion runs $9,000 to $14,000 and takes 5 to 8 working days of construction. The full cost breakdown is in our tub-to-shower conversion cost guide.

How Much Does a Walk-In Shower Cost in Phoenix?
At RDC, a custom tile walk-in shower built as a tub-to-shower conversion runs $9,000 to $14,000. A curbless entry usually adds about $3,000, depending on the existing floor and drain. A small bathroom remodel around a new shower starts at $9,000, and a primary bathroom at $18,000. Every RDC estimate is written, itemized, and free, with no obligation to move forward.
A tub-to-shower conversion takes 5 to 8 working days of construction when the drain stays where it is, 2 to 3 more if it moves, and the glass goes in about a week after the tile is set. A primary bathroom takes one to two weeks.
Example: a 60-inch alcove tub in a Phoenix hall bath is removed and rebuilt as a tiled walk-in shower with a bench, a niche and frameless glass. At RDC that scope runs $9,000 to $14,000 and takes 5 to 8 working days of construction, with the glass installed about a week after the tile.

How a Custom Shower Is Actually Built, Step by Step
Almost everything that determines whether a shower lasts happens before you ever see a tile. This is the sequence we follow, and it is worth reading because it gives you specific things to ask any contractor about.
- 1. In-home measure and showroom selection. We measure the bathroom, look at the plumbing wall and where the drain sits, and agree a layout; moving a drain is possible but changes the cost, so it gets settled now. You choose tile, grout, niche placement, bench, glass and fixtures at the showroom, together, so the finished room reads as one design.
- 2. Demolition to the studs. The old shower or tub, surround and substrate come out. This is where hidden water damage surfaces; if there is rot behind the old surround, it gets addressed before anything is rebuilt.
- 3. Plumbing rough-in. Valve, drain and any relocated supply lines are set. This work is coordinated with licensed plumbing partners.
- 4. Blocking and framing. Solid backing goes in for grab bars, benches and any wall-hung fixture, and the pan is framed and sloped, roughly 1/4 inch per foot toward the drain.
- 5. Waterproofing. A bonded waterproofing membrane (Schluter KERDI or RedGard) is applied across the pan, walls, corners and the drain connection. Corners and the curb, where there is one, are the two places showers actually fail, so they are detailed rather than simply covered.
- 6. Tile setting. Layout is planned so cuts land where they are least visible and niche edges align with the field tile instead of slicing awkwardly through it.
- 7. Grout and seal. Epoxy grout or professionally sealed grout as standard, because of Phoenix water.
- 8. Glass measure and install. Frameless glass is templated after tiling, since it has to be cut to the finished opening rather than the framed one. The glass shop needs about a week to fabricate it, so it is installed about a week after the tile is set.
- 9. Final walkthrough. We go through the finished shower with you, and the work carries a 1-year workmanship warranty.
Two questions from that list are worth putting to any contractor you are comparing: what waterproofing system do you use, and how do you detail the corners? A company that builds tile showers regularly answers immediately and specifically. Vague answers about "waterproof backer board" are a warning sign, because backer board on its own is not a waterproofing system.
