Bathroom remodeling in San Antonio is a hard-water project in a long hot season, with heavy rain as the leak test. Mineral etches shower glass, clogs heads, and seizes valves while the tile still looks presentable. Most baths sit on a slab, so the drain is where the concrete put it. Humid spells after a storm still grow mold if the fan is weak, then the air dries out and people forget until the next cloudburst. Scale is the constant.
Waterproof the wet wall as if the downpour will find it. Ask how the pan is built, where the membrane turns up at the curb and the niche, and whether the valve can be opened later without wrecking the tile. A roof leak over a bath is a common sequence here once hail cracks tile and rain follows. Do not close a new ceiling under an active stain. Run the fan to the outdoors. An attic in this heat is a poor place to dump shower air.
Plan the layout around the slab and the mineral. Moving a shower means opening concrete, and that should be said on the call, not discovered on demo day. Replace valves that are already packed with scale, and choose finishes that you can descale. Glass that etches will etch again unless the water is addressed, so say if every fixture in the house crusts up. That is a plumbing fact sitting in the middle of a remodel.
Older stone and plaster baths near the center of town hide uneven walls and showers that were never really waterproof. A new surface on that plaster, without a membrane, will look sharp until the next heavy rain finds the chimney flashing or the window joint. Ask what behind the tile is being corrected. If the floor cracked because the slab moved, tile will crack again. The forces here are mineral, heat, and storm water from above.
Describe the bath, confirm slab or an older wood floor, and name the problem: scale, a leak from the roof, a pan failure, or a layout locked by concrete. Mention cracked tile overhead if the last storm opened the roof. Ask who handles the membrane, the fan duct, and the valve. Call the number on this page.
