Before any demolition happens, three choices determine the entire build: what the pan is made of, whether the shower has a curb, and where the drain sits. Those decisions interact. A curbless entry on a slab is a different substrate problem from a curbed one. A linear drain along a wall lets the whole floor slope in one plane, which changes what tile is practical. A pre-formed acrylic or solid-surface base skips the tile floor entirely and, for some households, is genuinely the better answer. Working through these in the right order avoids the common outcome of picking a tile first and discovering it does not suit the floor you are building.
Scope of work
The pan itself comes in three broad approaches. A traditional mortar bed with a PVC or CPE liner and a clamping drain gives complete freedom on size and shape and is time-tested when built correctly. A pre-sloped foam tray with a bonded sheet or liquid membrane and a bonded-flange drain is faster, lighter, and removes the pre-slope mistake by design, at the cost of working within manufactured sizes unless it is cut and modified. A pre-formed acrylic or solid-surface base is the simplest and the least likely to leak, because it is a single molded piece — the trade is appearance and the fixed size range.
The curb decision comes next. A curbed shower contains water most reliably and is the least complicated build. A curbless entry looks better, is far easier to walk or roll into, and on an existing slab usually requires either recessing the slab in the shower footprint or raising the entire bathroom floor to create the fall. Neither is trivial and both should be decided before demolition.
Drain type follows. A center point drain slopes the floor from four directions, which suits smaller tile or mosaic. A linear drain at one wall or at the entry lets the floor slope in a single plane, which makes large-format tile practical and is often paired with curbless designs. The drain body must match the waterproofing system chosen, so this decision and the pan decision are made together.
What gets specified
For a household living through the work, the specification that matters most is the waterproofing system, because bonded sheet or liquid membranes over a pre-sloped tray reach a testable state faster than a traditional liner and double mortar bed and leave fewer wet layers in the assembly. Cement board or treated foam board replaces any paper-faced gypsum found behind the old tile. Dust control is equipment rather than material: zip barriers, a HEPA extractor on the grinder and saw, and wet cutting outdoors where possible. The pan-to-wall joint gets a flexible sealant rather than grout, because that joint moves. Setting materials and grouts should be chosen with the drying reality in mind, and a rapid-set product can shorten a wait, but only where the installer can work at its pace without compromising the layout.
What Houston conditions demand
Curbless is where the Houston slab matters most. In a house with a crawlspace, the floor structure can be dropped between joists to create the recess. On slab-on-grade, achieving a flush entry means either recessing the concrete in the shower footprint — with a tendon scan first on a post-tension slab — or building the whole bathroom floor up and creating a gentle ramp at the door. Both are legitimate; both change the scope substantially from a curbed build. Anyone quoting curbless on a slab as a minor upgrade has not thought about it.
Tile size interacts with the local reality too. Large-format tile on a slab that moves seasonally wants proper crack isolation and movement joints, and it works far better on a single-plane linear-drain slope than trying to warp a big tile in four directions toward a center drain. Small mosaic conforms to compound slopes easily but multiplies grout lines, and in an area with meaningful water hardness those grout lines collect mineral film.
Glass selection sits alongside this. Hard water spots show on shower glass here quickly, which is why factory-applied protective coatings and a squeegee habit come up in nearly every Houston shower conversation.
Houston homes and this work
Houston is not one housing stock, so it is not one kind of remodel. In the Heights and Woodland Heights you are often working on 1910s–1930s wood-frame homes on pier-and-beam, where leveling, sill and joist repair, and original wiring long past its service life come before anything cosmetic — and where a home in a designated historic district brings design review with it. Montrose, Oak Forest and Garden Oaks add mid-century layers. Meyerland, Westbury, Braeswood and Sharpstown are largely 1950s–60s slab ranch: cast iron drains near the end of their life, galvanized supply, single-pane windows, popcorn ceilings that should be tested before they are disturbed. Memorial and Alief lean 1970s–80s, which brings aluminum branch wiring and polybutylene supply into the conversation. West of Beltway 8 you are usually in 2000s and 2010s construction, where the job is upgrade rather than repair. Houston has no zoning, but plumbing, electrical and structural work is permitted, and deed restrictions still govern a great deal.
Common mistakes
Recaulking a moving joint and calling it a repair. If the membrane is gone, the sealant only hides where the water is entering. Second, missing the pre-slope on a rebuild, which is the classic liner failure and guarantees a permanently wet mortar bed. Third, packing mortar over the weep passages at the drain with no coarse aggregate to keep them open, so the liner has no way to drain. Fourth, fastening through the liner below the top of the curb, which puts holes exactly where water rises. Fifth, skipping the flood test, or running it after the mortar bed is in, when a failure can no longer be fixed cheaply. Sixth, tying a new pan into old wall tile without lapping the membrane up behind the wall board, which just relocates the leak. Seventh, leaving the exhaust fan undersized or ducted into the attic, so the new shower gets the same conditions that killed the old one.
Where the budget goes
The curb decision is the largest single fork. Curbed is the baseline. Curbless on slab adds either concrete recessing with scanning and structural care, or a raised floor across the whole bathroom with transitions handled at every doorway — both meaningful additions.
Pan system follows. A pre-formed base is generally the least expensive path and the least customizable. A foam tray with bonded membrane sits in the middle. A traditional mortar pan with a liner is the most flexible on shape and typically the most labor.
Then drain type — linear drains cost more than center drains as a component and often less in tile labor, which partly offsets. Tile format and pattern move labor a lot: mosaic on a compound slope is slow, large format on a single plane is faster but demands a flatter substrate.
Add shower size, niche and bench construction, whether the valve is being upgraded at the same time, glass configuration and coating, and any framing repair uncovered during demolition. The realistic range across these combinations is wide, which is why the choices above are worth settling before pricing anything.
The process
The first conversation is about how the shower is used and by whom. A household planning to stay in the house for decades often has good reasons for curbless and a bench; a household prioritizing a straightforward, reliable build may be better served by a curbed shower with a linear drain.
Once curb, pan system, and drain type are settled, tile is chosen to suit the slope geometry rather than the other way round. Then demolition, substrate inspection and repair, any slab recessing or floor build-up, drain set to match the system, pre-slope, waterproofing with reinforced corners and a wrapped curb, flood test, tile, grout, movement joints, glass, and sealed transitions.
Common questions
Can I have a curbless shower on a slab foundation?
Yes, but it is a real construction decision rather than a finish choice. On slab-on-grade the fall has to come from somewhere — either the concrete is recessed in the shower footprint, which requires scanning for post-tension tendons first, or the entire bathroom floor is built up and transitions are managed at the doorways. Both work. Both need to be planned before demolition, because they change the substrate for the whole room.
Is a linear drain better than a center drain?
It is better for some things. A linear drain lets the whole floor slope in one direction, which makes large-format tile practical and pairs naturally with curbless entries. A center drain requires the floor to slope from four directions, which suits small tile and mosaics. Neither is inherently more waterproof. Choose based on the tile you want and whether the entry is curbed, then match the drain body to the waterproofing system.
Should I use a pre-formed base instead of tile?
For some households, honestly yes. A molded acrylic or solid-surface base is a single piece with no grout on the floor, it is the least likely of the options to leak, and it is the easiest to clean — which matters in an area with hard water. The trade-offs are appearance and being limited to manufactured sizes. If the shower is a secondary bathroom or a rental, it is often the sensible choice.
