Bathroom Remodeling in Plano, TX

Plano is a boom-built city, and its bathrooms follow the boom. The census tells the story better than any sales pitch: 17,872 people in 1970, 72,331 by 1980, 128,713 by 1990, 222,030 by 2000. The corporate relocations of the 1980s built a suburb in two decades. The practical result is that the overwhelming majority of Plano's roughly 120,000 housing units are slab-on-grade production and semi-custom homes from about 1975 to 2005 — and the showers inside them were all built the same way.

That matters more than any design trend. A shower installed in Hunters Glen in the early 1980s, in Old Shepard Place around 1984, in Willow Bend West in 1988, or in Chase Oaks in the mid-1990s is not just dated. It is at the end of its service life, and it has been quietly wet for longer than most owners realize.

The Waterproofing in Your Shower Is Buried, and It Is 35 Years Old

Here is what we find when we demo an era-typical Plano master bath. A drop-in garden tub sitting in a tiled deck. A cramped corner shower next to it. Four-inch or six-inch wall tile, a cultured-marble top on an oak vanity, gold-tone trim. And under the shower floor, the system every builder used at the time: a sheet PVC or CPE pan liner laid on the subfloor, a mortar bed floated on top of the liner, and tile set into the mortar.

The critical thing to understand is that in that system, the tile is not the waterproofing and never was.Water gets through grout and tile — it always has. It soaks into the mortar bed and is supposed to drain out through the weep holes at the drain. If the liner was not pitched correctly to those weeps, or the weeps clogged with mortar during the original install, the bed simply stays saturated. Fine Homebuilding's teardown of the method is blunt about the consequence: the bed stays wet, weakens, and grows mold. There is no bonded membrane under the tile in these showers, because that approach did not become standard residential practice until well after these homes were built.

Home-inspection sources put a well-built pan liner at 40 to 50 years, but a typical tile-shower installation at closer to 20 — and PVC gets brittle as it ages and its plasticizers leach out. A 1988 shower is roughly twice past that 20-year mark. So when we open one up in Plano, the question is never whether the mortar bed is wet. The question is how far the wet has traveled: into the curb, up the studs behind the valve, out under the threshold into the bedroom's floor tile.

The rebuild answer is a bonded waterproofing membrane on the pan and the walls, so the membrane sits directly under the tile instead of two inches below it. The tile becomes the wear surface. Water that gets through the grout hits waterproofing immediately instead of soaking a mortar sandwich for a decade. We flood-test the pan before tile goes down, because the only cheap time to find a leak is before it is buried. More on the method on our shower remodeling and tile installation pages.

East Plano and West Plano Are Two Different Jobs

This is the part no other Plano bathroom page will tell you, and it is not marketing — it is geology. Plano sits on the boundary between two formations. Roughly west of the Dallas North Tollway, the slabs sit on Austin Chalk limestone, which is relatively stable, though it erodes slowly under slabs over decades. The eastern half of the city sits on Blackland Prairie clay — expansive smectite soil that swells when it takes on water and shrinks away from the slab when it dries out. Homes east of US 75 see the most slab movement and need the most piers when a foundation is repaired.

That seasonal shrink-swell cycle is what cracks the same grout line every summer, opens the joint where a tile floor meets a tub deck, and eventually cracks a brittle 30-year-old pan liner that had been holding fine until the slab moved under it. So we scope the two halves of Plano differently:

• East of US 75 — Hunters Glen and the older established neighborhoods: we build for movement. Uncoupling or crack-isolation membrane under the floor tile, movement joints at the perimeter and at every change of plane per the tile industry standards, flexible sealant instead of grout where the floor meets the wall. Rigid assemblies on moving clay are how you get a bathroom that looks cracked again in three summers.
• West of the Tollway — Willow Bend West, Ridgeview Ranch, and the west-Plano custom builds: the slab is usually the lesser risk (thin clay caps over the chalk still move some). The bigger risk in these homes is the aging liner and the original drain assembly, which is exactly what a proper gut-and-rebuild replaces.

If your floors have already moved, our guide to flooring for foundation movement in Texas covers the same principle across the rest of the house.

The Permit Line Is Where Honest Contractors Separate From Cheap Ones

The remodel Plano homeowners want most — remove the garden tub and the corner shower, combine that footprint into one big zero-entry walk-in — moves the shower drain. That is not a detail. It is the whole legal difference between two jobs.

The City of Plano's Building Inspections handout on when a permit is required is specific: cosmetic work like painting, wallpapering, carpeting, cabinets and trim does not require a permit, and swapping fixtures onto existing plumbing does not either. Plumbing work does. Adding or replacing walls does. Relocating a shower drain is plumbing work, full stop. The same department states that contractors must be registered with the city before doing any work, warns homeowners never to use a contractor who says no permits or inspections are required, and tells you to be especially wary of a contractor who suggests you obtain the permits for their work — because the permit holder owns the liability.

So we will say it plainly. On a Plano tub-to-shower conversion, we pull the plumbing permit as a registered contractor working with a licensed plumber. We do not ask you to pull it. The relocated drain gets inspected before the pan goes over it and disappears under tile for the next thirty years. And if your neighborhood has an HOA — common in west Plano and in the post-1990 subdivisions — Plano's own guidance tells homeowners to check deed restrictions and covenants, which matters the moment a debris trailer parks at your curb.

Where We Work in Plano

Hunters Glen, with its 1970s and 1980s ranch and contemporary-colonial plans around Jack Carter Park. Old Shepard Place, where most of the houses went up around 1984. Willow Bend West, the late-1980s-through-1990s custom homes off the Tollway. Chase Oaks, developed through the 1990s. Ridgeview Ranch up in 75025, mostly late-1990s to early-2000s. Every one of those is a different vintage of the same underlying shower system, which is why the demo tells us more than the address does.

Two exceptions worth naming. The heritage districts downtown — Haggard Park, Old Towne, the Douglass Community — hold the only meaningful pre-war, non-slab housing in Plano, and a pier-and-beam bath is a genuinely different animal from a slab bath. And the newer mid-rise and condo units around Legacy West are stacked construction, not slab-on-grade, so sound isolation and building rules drive the scope more than soil does. We will tell you which conversation we are having on the estimate.

At Home Flooring Solutions has run a real showroom at 1001 Alanis Dr Ste 120 in Wylie since 2019 — about a 25-minute drive from most of Plano, and worth the trip when you are choosing tile, because a 12x24 porcelain looks nothing on a phone screen like it does underfoot. Ramzi, our lead installer and co-owner, has 15+ years in the trade, and the tile work in your bathroom is done by the company you hired, not marked up through a general contractor.

Free in-home estimate anywhere in Plano: we measure, we look hard at the existing shower, and we leave a written line-item quote. Financing is available on qualifying projects. If you want to see finished work first, the project gallery is the place to start.
