What Kind of Contractor Do I Need for a Bathroom Remodel?
A bathroom is a small room that packs in more trades per square foot than almost anywhere in the house. Water, waterproofing, tile, electrical, and ventilation all meet in a tight space, and the order they go in — especially the hidden waterproofing under the tile — is what separates a bathroom that lasts twenty years from one that leaks in two.
The 6 trades this job usually needs
A single problem often spans several trades. Here is who does what, and why.
Remove the old fixtures, tile, and vanity.
The room has to be taken back to the studs for a full remodel.
Move or update supply and drain lines for the tub, shower, toilet, and vanity.
New layouts and fixtures almost always change the plumbing.
Add or update GFCI outlets, lighting, and the exhaust fan to code.
Bathrooms need ground-fault protection and proper ventilation for safety and moisture control.
Waterproof the wet areas, then set the tile for the shower, floor, and walls.
The waterproofing behind the tile is what prevents hidden leaks and rot — it has to be done right and in order.
Install the vanity and top.
Fitted after the wet work is done.

Do I need a general contractor for a bathroom remodel?
For a full remodel, usually yes — a bathroom packs plumbing, electrical, waterproofing, and tile into a tight space and a specific order, and a general contractor coordinates them. Swapping a vanity or re-caulking you can handle directly or with a single trade.
What is the most important part of a bathroom remodel?
The waterproofing behind the tile in the wet areas. It is invisible when finished, but doing it right is what prevents leaks, rot, and mold down the line.
Do I need permits for a bathroom remodel?
Usually, once you move plumbing or add electrical. Your contractor typically pulls them; unpermitted bathroom work can cause problems at resale.
How long does a bathroom remodel take?
A typical full remodel runs a few weeks depending on scope and tile work, plus time for materials and any custom items to arrive.
