Bathroom remodel decision guides

Does the plumbing move? This is the fork in the road. A same-footprint remodel is a predictable job. Relocating the toilet or shower drain means opening the floor, and in a slab-on-grade house that means cutting concrete. Only 5% of homeowners relocate the bathroom entirely, and 36% change the layout at all, per Houzz. Most people are right not to.

Living in it or selling it? If you are selling within a year, fix defects and refresh surfaces. The 2025 Cost vs. Value Report has midrange bathroom remodels around 80% cost recouped nationally, meaning you still lose money on the transaction. If you are staying ten years, buy what you want and stop doing resale math.

Will it work when you are older? 68% of homeowners now factor special needs into bathroom projects, and 49% are planning for aging household members, per Houzz. Blocking in the walls for future grab bars costs almost nothing during a remodel and is expensive to add later. Non-slip flooring (chosen by 55% of those addressing aging in place) and a low or no curb are the other two decisions that are cheap now and costly later.

One decision that is genuinely a bad idea: tiling over a shower that has leaked. If you have seen water in a ceiling below, in an adjacent closet, or soft floor at the base of the toilet, the fix is demolition and repair. A new surface over wet framing buys a few years and a bigger bill.

How to choose

Answer 'does the drain move' first

Everything downstream — budget, permits, schedule — follows from this one answer.

Add blocking for grab bars even if you don't want them yet

Plywood behind the tile while the walls are open is trivial. Retrofitting anchors into finished tile is not.

Fix the ventilation while the ceiling is open

The IRC requires bathroom exhaust of at least 50 cfm intermittent or 20 cfm continuous. Undersized or unvented fans are the root cause of most mold complaints.

If there has been a leak, investigate before you design

Open the wall or get a moisture reading. Designing around unknown damage guarantees a change order.

Deciding under a countdown clock is how people buy the wrong scope. Take a week.
