How long does a custom tile shower take to build?

It depends on the size, the tile format and whether plumbing moves, but the sequence is fixed: demolition, framing and rough-in, waterproofing and a flood test, tile, then grout and glass. The flood test and grout cure are not steps that can be compressed, so we schedule around them rather than through them.

Is a tile shower harder to maintain than an acrylic unit?

It has grout joints, so it is not maintenance-free. Modern grouts and larger tile formats reduce joint length considerably, and the trade is that a tile shower can be repaired, re-grouted and re-sealed for decades, where a cracked acrylic pan is replaced.

Can you tile over the existing shower pan?

No. Tiling over an unknown pan of unknown age means inheriting whatever failure is already underway beneath it, with no way to test it. We remove the existing wet area to the framing so the waterproofing can be built as one continuous system.

Do you supply the tile or do we?

Either. Many clients choose tile at a local showroom and we set it; others ask us to develop the whole scheme. If you are buying, we will tell you the quantity to order including waste allowance and confirm the tile suits a wet, hard-water environment before you commit.

Custom Tile Showers in Meridian, Idaho

A shower designed around your room's real dimensions, then set tile by tile so the layout lands where it should.

Short answer

A custom tile shower is built on site from separate components — a sloped and waterproofed substrate, a drain assembly matched to that waterproofing, and tile set into the finished enclosure. Unlike a moulded acrylic unit, nothing about it is fixed in advance, so the size, the tile layout, the niche positions and the glass line are all decisions. The quality of a custom shower is decided in the two layers you never see again once tile goes on.

What “custom” actually changes

Most showers in Treasure Valley homes were sized by whatever fibreglass unit fit the framing when the house was built. A custom shower starts from the opposite end: we measure the room, decide how large the wet area can reasonably be, and then build the enclosure to that dimension. The practical result is usually a shower several inches wider, with the controls where you can reach them before stepping into the spray.

The footprint follows the room, not a stock pan size
Tile layout is planned so cuts fall at the least visible edges
Niches, benches and grab-bar blocking are framed in from the start
Valve and head heights are set for the people who use the shower
Glass is measured to the finished tile, not ordered off a shelf

Tile layout is a drawing, not an improvisation

Before any tile is set, the walls get laid out full size. We establish the horizontal datum, decide which wall the eye reads first, and work the courses so that the top of the niche aligns with a grout joint rather than cutting through the middle of a tile. Where the shower has a curbless entry, the floor layout is set from the door opening back, so the visible run of tile stays uninterrupted.

A sliver cut at eye level is the single most common tell of a rushed tile shower. Avoiding it costs planning time, not material.

How tile format affects a shower build
Tile format	What it does well	What it demands
Large-format porcelain (24×48 and up)	Very few grout joints, calm modern surfaces, easy to clean	Extremely flat substrate, back-buttering, careful lippage control
Standard field tile (12×24, 4×12)	Forgiving, wide selection, straightforward repairs	Layout discipline so courses stay level around niches
Handmade and zellige-style ceramic	Depth and light movement no printed tile reproduces	Wider joints, accepted variation, slower setting
Mosaic and small-format	Slope tolerance, higher slip resistance on floors	More grout to seal and maintain, careful sheet alignment
Natural stone	Genuine variation and a soft, honed surface	Sealing, sensitivity to acidic cleaners, heavier substrate needs

What sits under the tile

Tile is a wear surface. It is not, and has never been, waterproof — grout joints pass water and so does the setting bed behind them. A custom tile shower only lasts if the layer behind the tile is a continuous, tested waterproofing system tied into the drain. That is why our tile work and our waterproofing are never quoted as separate trades.

1Framing corrected to plumb and square, blocking added where anything will be fastened
2Substrate installed: foam board or cement board depending on the system
3Sloped floor formed to the drain at a consistent, verified fall
4Waterproofing membrane, banded corners and a matched drain flange
5Flood test held before a single tile is set
6Tile set, then grouted and sealed after cure

Building for Treasure Valley water

Groundwater across much of Ada and Canyon County is hard, and it shows on shower surfaces faster than homeowners expect. That informs real specification choices: through-body or glazed porcelain over highly polished finishes, a grout that will not etch under routine descaling, and glass that has been given a factory-applied protective treatment rather than left bare. We would rather choose a surface that survives your cleaning routine than one that photographs well for a month.
