How to Plan a Bathroom Remodel in 30 Minutes

Updated September 2026 · 6 min read

Most bathroom projects stall in the same place: months of saving images, no decisions. The gap isn't information — it's that nobody has written down what the project actually is.

Half an hour and a sheet of paper closes that gap. Not a finished plan, but the six decisions everything else depends on. Set a timer and work in order; the order is doing real work.

0–5: Name the problems, not the products

Write what is wrong with the bathroom you have. Not what you want it to look like — what irritates you. "No storage." "Shower is cramped." "Awful light at the mirror." "Mould in the corner." "Feels dated."

Then mark each one:

• M — must fix. Anything failing: leaks, rot, no ventilation, unsafe wiring.
• W — want to fix. Daily irritations.
• N — nice to have. Aesthetics.

This list is what protects you later. Budgets always tighten, and when yours does you want to cut from the bottom. Without the list you'll cut whatever is least visible — which is usually the M items.

5–10: Fix the ceiling

Write the maximum you can spend without regretting it. One number. Then multiply by 0.85 and write that number underneath — the 15% difference is contingency and it is not available.

Plan the whole project against the lower number.

Bathrooms conceal their problems behind tile and under floors. Demolition regularly turns up rot, failed subfloor, or wiring that isn't to code — none of which anyone could quote in advance. A 15% reserve turns each of those into a phone call rather than a crisis, and if you don't touch it, you keep it.

For what different scopes actually cost, see our budgeting guide. The short version: labour is typically 40–55% of the total, so a budget built from material prices will come in low.

10–15: Answer the plumbing question

One question, and it moves your budget more than every material choice combined:

Does the toilet, sink or shower move?

Keeping fixtures where they are keeps a remodel in a predictable band. Moving them means opening the floor, re-routing drain lines at the correct slope, and turning a plumber's hours into days. It's routinely the difference between a mid-range project and a top-of-range one.

So spend these five minutes genuinely testing whether the current arrangement can work. Can the storage problem be solved with a better vanity and a recessed cabinet rather than a new wall? Can the shower be enlarged into the tub's footprint instead of relocated?

Sometimes the answer is genuinely no — a bad layout, real accessibility needs. But "it would look better over there" is an expensive sentence, and this is the moment to catch it.

15–20: Draw the scope

Now list the actual jobs. Go around the room and mark each in or out:

• Shower / tub — new walk-in shower, tub-to-shower conversion, new tub, new wall tile, new floor tile, bench or niche, new glass or door
• Vanity & toilet — new vanity and sink, countertop, mirror, vanity lighting, replace toilet
• Flooring & walls — floor tile, heated floors, drywall repair, paint, decorative tile
• Electrical & ventilation — new lighting or circuits, new exhaust fan
• Finishing — window, towel bars, hooks, accessories

Be honest about the "in" column. It's tempting to include everything; the ranked problem list from step one tells you what earns its place.

This list is the seed of a scope of work — the document that later makes contractor bids comparable. See what to include in a scope of work.

20–25: Shortlist a direction, not products

Five minutes is not enough to choose tile, and trying is how people lose an evening. Instead decide the constraints that narrow the choice later:

• Light or dark overall
• Warm or cool tones
• Metal finish — chrome, brushed nickel, matte black, brass — pick one and apply it everywhere
• Floor tile size — and remember a centre-drain shower floor needs small tile; large format needs a linear drain
• One thing you'll spend on and one you'll economise on

That's five constraints, and they eliminate about ninety percent of the catalogue. Actual product selection happens later — but it must all be finished before demolition, because unmade decisions become change orders.

25–30: Write the next three actions

End with three specific, dated things. Not "research contractors" — that isn't an action. Something like:

1. Tuesday: call the county building department, describe the scope, ask whether it needs a permit
2. Thursday: measure the bathroom properly — length, width, ceiling height, window and door positions, vanity wall
3. Saturday: visit one tile showroom with the five constraints written down

Three actions with days attached is what separates a project that starts from one that stays a folder of images.

What you have after 30 minutes

That is genuinely enough to have a useful conversation with a contractor, and considerably more than most homeowners bring to a first meeting.
