Bathroom Remodel Planning Checklist

Why decision order matters

Bathroom remodels involve dozens of individual decisions, and making them in the wrong order is one of the most common sources of budget creep and delay. Layout decisions affect plumbing, plumbing affects rough-in dimensions, rough-in dimensions affect which fixtures fit, and fixture choices affect tile layout. Working through decisions roughly in this sequence keeps each choice grounded in what came before it, rather than forcing rework later.

Planning checklist: decision order

1. 1

   Define goals & layout

   Decide whether the current layout stays or changes — tub-to-shower conversion, wall removal, or reconfigured footprint — since this drives every downstream decision.

2. 2

   Set a budget range

   Use planning ranges and the cost calculator to establish a target range before finishes are chosen, so selections stay grounded in reality.

3. 3

   Take key measurements

   Room dimensions, ceiling height, window and door placement, and existing plumbing/electrical locations.

4. 4

   Choose the shower or tub system

   Walk-in shower with linear drain, alcove tub, or freestanding tub — this decision affects plumbing rough-in and waterproofing scope.

5. 5

   Select tile & flooring

   Format, material and pattern for shower walls, floor and any accent areas; confirm lead times for special-order products.

6. 6

   Select vanity & countertop

   Sizing, single vs. double vanity, storage needs, and countertop material.

7. 7

   Select fixtures & lighting

   Faucets, shower valve/head, toilet, mirrors, and layered lighting (ambient, task, accent).

8. 8

   Confirm permits & approvals

   Where applicable, confirm municipal permit needs and any condo/HOA approval steps before demolition begins.

Measurements worth gathering early

• Overall room length, width and ceiling height
• Door swing direction and clear width
• Window location, size and sill height
• Distance from existing drain to nearest wall
• Location of existing electrical outlets and switches
• Ventilation/exhaust fan location and duct run
• Any structural elements like load-bearing walls or plumbing chases

Understanding allowances

Many project budgets include allowances — a placeholder dollar figure for categories like tile, plumbing fixtures or lighting before an exact product has been selected. Allowances are useful for keeping planning moving, but they only work well if you choose your actual products promptly. If a final selection exceeds its allowance, the difference is generally handled as a change order rather than absorbed automatically into the original budget.

How change orders work

A change order documents any change to the agreed scope after work has started — an upgraded countertop, an added niche, a different tile pattern, or a layout tweak discovered once demolition reveals existing conditions. Change orders typically specify the added (or reduced) cost and any schedule impact, and should always be documented in writing before the change is made, so both budget and expectations stay aligned.

A final planning tip

The more decisions you lock in before demolition — layout, shower system, tile, vanity, fixtures — the fewer change orders and delays you're likely to encounter.
