Name the waterproofing before the tile is picked

A bathroom remodel is a wet room that has to survive Florida humidity after the new faucet is boring. The shower assembly matters more than the finish. The scope names the waterproofing: a liquid membrane, a sheet membrane, or a formed pan and liner, including where it laps at the curb, the niche, and the bench. Tile on a backer board, with no system named, is not a shower scope. It is a hope that the setter’s habit matches the house.

Before tile, the waterproofing gets the check that system calls for. On a liner or a sheet that means flooding the pan and looking for the water you do not want to find later. A liquid membrane gets the cure that product wants. We do not tile the same day we coat a wall if the coating is still soft. Niches, benches, and the curb are part of that layer. They are not tile details invented after the board is up. The mixing valve is a selection in the same scope, with access if that valve needs it.

The board behind the tile is not the waterproof layer

Paper-faced drywall does not belong inside a shower. Moisture-resistant board, the green or purple sheet people ask for by nickname, is for damp walls, such as beside a vanity. It is not the inside of a shower. Screw holes and joints pass water. Cement board and fiber-cement backer are substrates. They are still not the waterproofing. Water will find the fasteners. The membrane, or a named manufactured system, is what keeps the wall dry.

Where wet-area board starts and stops

Wet-area board means a backer rated for the wet zone: cement board, fiber-cement, or a glass-mat board the manufacturer rates for that use. The scope names which one, and where it stops. If the assembly relies on a coated backer and sealed joints instead of a full membrane, the scope names that product and the joint treatment. We do not write green board and tile and hope. Outside the splash, ordinary drywall can return, but the joint between wet board and dry board sits outside the wet zone, not in it.

A curb or a linear drain is a plumbing decision

A curb is the simpler way to keep water in the shower on a slab house. The pan slopes to a drain, the curb gets waterproofed as its own piece, and the bathroom floor outside can stay at a normal height. It is not old-fashioned. It is a shape that works when you cannot sink the shower into the structure. A lot of Ocala baths are on slab. You do not get a spa floor by wishing the concrete were thinner.

A linear drain is a different geometry. The floor falls in one plane to a long drain, often at the entry or along the back wall. Curbless, where the bath floor and the shower floor want to be nearly the same height, usually means a raised floor in the rest of the room or a recessed shower. Recessing a structural slab is not a casual line. If the slab cannot give you the fall, the drain style changes or the floor build-up changes. We do not hide a flat floor in extra thinset and call it pitched.

Glass, the curb width, and the door swing matter in a small hall bath before anything is demoed. A beautiful panel that blocks the vanity is a layout error. A tub-to-shower change is plumbing and framing, not a surround kit hung on the old valve. The old valve, the trap, and the mixed water lines get replaced or reused on purpose, written down, not discovered when the tub is already in the yard.

The fan has to reach the outside

A new bath with a fan blowing into the attic will grow mold no matter how good the tile is. The duct runs to a wall cap or a roof cap, with a damper that is not stuck shut. It does not dump on the underside of the roof deck. In a hot attic the duct is insulated so it does not rain condensation back down the fan housing. Short and as straight as the framing allows beats a long crushed flex line that the fan cannot push.

The switch has to be one the household will actually use. A fan hidden on a timer nobody was shown does not count. A window is not the August plan, even if the sash works. If that window sits in the wet wall, the leak at the frame is part of the job, and the window gets flashed instead of buried in new tile. The fan path is in the scope on every bath we remodel, not as an add-on if someone remembers.

The rest of the room still lives in wet air

The vanity wall takes splash and steam even when it is outside the shower. Stops that actually shut off, a trap that can be serviced, and a floor surface that can take water are part of the room. The floor outside the shower is not always sloped, so the finish has to tolerate a wet foot and a towel that never quite dries in July. Paint and paper-faced board stop where the splash stops. If you are doing more than this bath, the whole-home sequence decides whether this room stays available while another bath is open.

Plumbing that moves, a new fan circuit, and any framing change are permit items for the jurisdiction on that parcel. City of Ocala and Marion County are not interchangeable just because the mail says Ocala. The building permits page is the plain version. The counter is the official one. Which finishes are in this contract, and which rooms wait, still belongs in the home remodeling scope before the old tile comes off.

• Name the waterproofing system, the laps, and the test before any tile is chosen.
• Use wet-area backer in the shower. Do not put moisture-resistant paper-faced board in the wet zone.
• Pick a curb or a linear drain from the slab you have, not from a photograph.
• Duct the fan to a cap on the outside, and insulate the run through the attic.
• Treat a tub-to-shower change as plumbing and framing, not as a kit on the old valve.
• Keep one other bath usable if people are living in the house.

The shower fails behind the tile, not on the color you picked

A niche, a valve, and a floor that meets the hall

A shampoo niche is a hole in the waterproofing unless the membrane wraps it. We treat it as part of the system, not as a shelf the tile setter invents on Friday. The valve height is a decision before the wall closes, because a valve behind a new trim that you cannot reach is a future demolition. If the bathroom floor is tile and the hall is not, the heights have to be set together. A transition you can feel with your toe is a trip. Curbless showers make that problem stricter, because the whole bathroom floor may need to slope, not just the pan.

What we do when the old pan is already soft

If the floor gives underfoot or the ceiling below is stained, the assembly is already wet. Covering it with new tile is how you buy the same leak. The scope should say the old pan comes out, what is under it gets looked at, and how a rotten subfloor or a soaked slab edge is priced when it shows up. We do not bid a “refresh” over a soft floor and call it honest.

Fans, tubs, and block walls

The fan has to duct to an exterior cap. Blowing into the attic or the soffit leaves the moisture in the building, which is the problem a Florida bath already has. A cast-iron tub is heavy. Taking one out of a tight room is labor, and the path to the dumpster matters if you are living in the rest of the house. Grab bars, if you want them, need blocking. On a block wall that blocking is planned. Wood screws into tile do not hold a person. Ocala Building Contractor is a disabled veteran-owned business with 27+ years of construction experience.

One bathroom has to survive if you only have one

If this is the only bath, the schedule says where you will shower while it is out, or we phase the work so you are not locked out of the house. That is not a personal detail. It is the reason some one-bath remodels take a different shape than a guest bath you can close for three weeks. Tell us which it is on the first call.

Toilets and lavatories are the easy fixtures to talk about and the easy ones to get wrong in the rough. The flange height has to meet the finished floor, not the slab you can see today. A vanity that is wider than the old one can cover a vent or crowd the door swing. Measure the door. A bathroom that looks larger on a mood board and then will not accept the door is a layout failure. Glass, if you want it at the shower, needs a curb or a detail that the glass company can actually set. We do not design a panel that only works in the rendering.

Ventilation still matters after the tile is done. The fan grille is not decorative. If the duct is a long floppy run with sags, it holds water and the fan quits doing the job you bought it for. Short, supported, and ending at a cap on the outside: that is the standard. In this climate the bath is where humidity goes to live if you give it a place. We do not give it the attic. The same rule applies to the shower door and the bath floor outside the pan. Water that escapes a curb has to have a floor that can dry, and a baseboard that is not raw MDF waiting to swell. Those edges are in the scope because they are where a pretty bath starts to look cheap six months later. A bath that looks finished and cannot dry is not finished.
