Bathroom remodel mistakes to avoid

Most bathroom problems show up years later, behind the tile or in the ceiling. These are the mistakes we see most and how to avoid them.

Skimping on waterproofing

Tile and grout are not waterproof. A proper membrane behind and under the shower is what keeps water out of the walls. See custom tile showers.

Weak ventilation

An undersized or noisy fan that nobody runs leads to mold and peeling paint. Size it right with the bath fan calculator and put it on a timer.

One light over the mirror

A single fixture above the mirror casts shadows on your face. Add light at the sides or a lit mirror. See the bathroom lighting guide.

Too little storage

Plan a niche in the shower, drawers in the vanity and a linen spot. See bathroom storage ideas.

Forgetting the future

Add blocking for grab bars now and consider a curbless shower; see the grab bars guide and aging in place.

Common questions

What is the biggest bathroom remodel mistake?

Poor waterproofing. Tile and grout are not waterproof, so the membrane underneath is critical.

Do I need a bathroom exhaust fan?

Yes. A properly sized fan vented outside prevents moisture damage and mold.

How much storage does a bathroom need?

At minimum, vanity drawers, a shower niche and a spot for towels and linens.
