Complete Waterproofing System
A continuous waterproof membrane behind every wall and under every floor tile — the layer that decides whether a shower lasts.

Custom Tile Shower Installation in Riverside, CA

Built In, Not Bolted On
What Does a Custom Tile Shower Include?
A custom shower from JM Custom Tile and Stone is built from the framing out: a complete waterproofing system, a hand-sloped pan, recessed niches, tiled benches, glass-ready edges, and pebble or mosaic floors — every element planned together and installed by the same father-and-son team.
Sloped Shower Pan
A mortar pan pitched toward the drain so water never stands on the floor — built by hand and checked before tile goes down.
Recessed Niches
Storage built into the wall itself, waterproofed and trimmed in tile — no wire caddies, no shelves glued on afterward.
Tiled Benches & Curbs
Seats and curbs framed into the shower, sloped so water sheds off, and wrapped in the same tile as the walls.
Glass-Ready Edges
Walls and curbs finished plumb, square, and true so frameless or black-frame glass seats cleanly and seals tight.
Pebble & Mosaic Floors
Hand-set pebble and mosaic shower floors that grip underfoot and follow the pan's slope stone by stone.

The Part You Never See
Inside a JM Custom Shower Wall
The tile is the only layer you'll ever look at — but it's the three layers behind it that keep water out of your walls. Here is the assembly we build on every shower, from the framing out.
-
1
Tile & Grout
The finish layer — subway, herringbone, large-format, stone, or mosaic. Beautiful, durable, and not waterproof on its own.
-
2
Mortar Bed
Thin-set mortar rated for wet areas bonds every tile flat and full — no hollow spots, no corners buttered thin to save time.
-
3
Waterproofing Membrane
The layer that actually keeps your walls dry. Continuous across every surface, sealed at every seam, corner, niche, and bench.
-
4
Cement Backer Substrate
Cement board fastened to the framing gives the whole assembly a rigid, moisture-stable foundation — never bare drywall in a shower.
Where Cheap Showers Fail
Waterproofing Is the Whole Job
When a shower fails, it almost never fails at the tile. It fails behind it — a membrane that was skipped, a pan that wasn't sloped, a niche that was cut in after the waterproofing was done. By the time loose tile, dark grout lines, or a musty smell show up, the water has been getting into the framing for a long time.
That's why JM Custom Tile and Stone treats the waterproofing assembly as the job itself, not prep work. The membrane runs continuous across walls, pan, curb, niches, and benches, and it's inspected before any tile covers it. It's the difference between a shower that photographs well on day one and a shower that's still tight decades in.

Straight Answers
Custom Shower Questions, Answered
Who installs custom tile showers in Riverside, CA?
JM Custom Tile and Stone, a father-and-son tile company based in the Orangecrest neighborhood of Riverside (92508), installs custom tile showers throughout Riverside, Corona, and Moreno Valley. Owner Jody Madden brings 40 years of tile experience and more than 1,500 completed projects, and he guarantees every shower the company builds.
What keeps a custom tile shower from leaking?
The waterproofing assembly behind the tile. Tile and grout are not waterproof on their own — the membrane, the sloped shower pan, and sealed corners, seams, and penetrations underneath do the real work. JM Custom Tile and Stone builds the complete waterproofing system on every shower before a single tile is set, because that hidden layer decides whether a shower lasts.
Can you build a niche, bench, or pebble floor into my shower?
Yes. Recessed niches, tiled benches, curbs, and pebble or mosaic shower floors are framed, waterproofed, and tiled as part of the same shower assembly — not added on afterward. Because these features are planned into the layout from the start, grout lines stay aligned and the waterproofing stays continuous around every shelf and seat.
Do you build showers ready for frameless glass enclosures?
Yes. JM Custom Tile and Stone builds shower walls and curbs plumb, square, and true so frameless and black-frame glass enclosures seat cleanly against the tile. Glass installers measure off our finished edges, so the precision of the tile work directly determines how well the enclosure fits and seals.
Is JM Custom Tile and Stone licensed and insured?
Yes. JM Custom Tile and Stone holds CSLB license #956305 in the C-54 tile classification and is bonded and insured. Jody Madden guarantees all of the company's work, and the team leaves every house cleaner than it was before the job began.
