Bathroom Remodel Checklist for San Jose Homes: What to Decide First
Decide the layout first, then the shower or tub, the waterproofing, the fan, and the clearances. Those choices affect plumbing, framing, and the permit, so they need to be settled before demolition. Tile and fixtures come after.
In San José, the City lists key requirements for minor bathroom remodels, such as fan size and shower dimensions. They are included below so the design meets them from the start.
Start with how the bathroom is used
A primary bathroom may need more storage and a larger shower. A kids’ or guest bathroom may need a tub and durable finishes. Write down what doesn’t work today, such as a hard-to-use tub, too little storage, or poor light, before you pick materials.
Decide whether fixtures will move
Keeping the toilet, vanity, and shower or tub where they are keeps the plumbing simpler. Moving or adding fixtures can make the room work better, but in San José it turns the project into a major remodel with plans and plan review. Our San José permit guide explains the difference.
Tub, tub-to-shower conversion, or walk-in shower?
Replacing a tub with a shower and enlarging an existing shower are different jobs. Our two local project examples compare a San Jose tub-to-curbless-shower conversion with a Campbell shower expansion, and our guide to curbless showers explains how the water stays in without a curb.
If you remove the only tub in the house, think about who in the household still needs one.
Treat waterproofing as a system
Tile alone doesn’t make a shower waterproof. The membrane or system behind and under the tile, the slope to the drain, and how corners, niches, and valve openings are sealed do that work. Ask which waterproofing system will be used and how it will be checked before tile goes on.
You can see this stage on Landford’s Campbell shower expansion, where the project page shows the demolition and the waterproofing before tile.
Plan the shower fixtures before the walls close
Extra fixtures need plumbing planned early. A client in Saratoga asked for a handheld spray wand separate from the main shower head, and Landford made it work by reworking the plumbing, as the client’s Google review describes. That shower has a built-in bench, a rainfall showerhead, a handheld sprayer, and body sprays.
Plan the fan and the light switch
The City of San José’s key requirements for minor bathroom remodels say a bathroom with a tub or shower needs an exhaust fan of at least 50 CFM, Energy Star rated and ducted to the outside. An openable window doesn’t count. At least one light in the bathroom has to be on an occupancy or vacancy sensor that turns it off automatically.
Check the clearances on paper
The City’s key requirements for minor bathroom remodels also include:
- At least 15 inches from the center of the toilet to a wall or barrier on each side, and 24 inches of clear space in front
- A shower pan of at least 1,024 square inches and at least 30 inches in any direction
- A shower door with at least a 22-inch opening
Layer the lighting
- General ceiling light
- Even light at the mirror
- A light suitable for the shower
- A night light
- Daylight with privacy, if there is a window
Confirm these before demolition
- Fixture locations
- Vanity size and storage
- Shower or tub type and entry
- Waterproofing system
- Tile and grout
- Fan size and duct route
- Lights, switches, and the sensor
- Door and drawer clearances
- Who handles the permit
- Which bathroom you’ll use during the work
How Landford Construction handles bathroom remodels
Landford Construction does bathroom remodels in San Jose, the South Bay, and the Peninsula, including tub-to-shower conversions, walk-in showers, waterproofing, tile, and vanities. Landford applies for the permit, updates you after each stage and inspection, and walks through the finished bathroom with you. If this is the only bathroom in the house, read about living at home during a remodel.
Send photos of your bathroom, and for suitable projects Adam gives a free preliminary price range before a site visit.
The bottom line
Settle the layout, shower, waterproofing, fan, and clearances first. The finishes you see last only work if the parts behind them are right.
