Step-By-Step Plan For Bathroom Renovations
| Decision | Why it matters | Quick check |
|---|---|---|
| Wet-area finishes | Wet zones need durable, easy-clean surfaces. | Choose materials rated for bathrooms and simple maintenance. |
| Ventilation | Helps prevent humidity and long-term damage. | Confirm fan sizing and vent routing. |
| Layout | Good layout improves daily usability. | Verify clearances and door swings. |
| Budget control | Keeps scope creep from blowing up the price. | Use allowances and a written change-order process. |
Homeowners usually call a project the best when it holds up: no leaks, no peeling paint, and no mystery gaps in the contract. Additionally, For bathroom renovations, that outcome depends on two things you control early: who you hire and how clearly the scope is written.
Step-By-Step Plan For Hiring
- Define the scope: keep or relocate plumbing, also choose shower vs tub, and note ventilation, lighting, and storage needs.
- Shortlist 3-5 companies: focus on remodel experience, not just new builds.
- Request a site walk: a serious bid needs measurements, photos, and access to the electrical panel and shutoffs.
- Get a written proposal: look for itemized work, allowances, exclusions, and a start-to-finish schedule.
- Verify credentials: confirm the contractor’s California license status and ask for current insurance documentation.
- Compare bids on details: low numbers often hide missing waterproofing steps, fixture assumptions, or disposal.
- Sign with clarity: payment milestones, change orders, and warranty terms should be written and easy to understand.
Contractor Questions That Reveal Real Quality
- Who will supervise the job day-to-day, and how do I reach that person during the week?
- Which trades do you use for plumbing and electrical, and how do you coordinate inspections?
- What waterproofing method do you use in showers, and how do you document it before tile goes up?
- How do you handle hidden conditions (rot, damaged subfloor, old plumbing) when you find them?
- What is included in protection and cleanup (dust control, hauling, daily site reset)?
- What does your change-order process look like, and when do you require approval?
Red Flags Worth Walking Away From
- Vague bids that don’t list materials, allowances, or what’s excluded.
- Pressure to start demo before fixtures and tile are ordered.
- Requests for full payment upfront, or a contract without a clear payment schedule.
- Reluctance to talk about permits, inspections, or who is responsible for pulling them.

Decisions To Make Before Demo For Bathroom Renovations
The fastest way to blow up a budget is to start demolition while key decisions are still TBD. Overall, Contractors can’t price what isn’t defined, so vague selections turn into allowances and change orders. As a result, Use this checklist to keep bids comparable and make sure every company is quoting the same job.
Bid-Ready Scope Sheet (Use The Same List For Every Bidder)
- Layout: keep plumbing where it is, or move shower, toilet, or vanity? Note any wall changes.
- Shower/tub: size, curb vs curbless, niche vs shelving, and the shower door style.
- Vanity: width, single vs double sink, countertop material, and mirror/medicine cabinet plan.
- Flooring: tile type and size, heated floor or not, and transition details at the doorway.
- Lighting & electrical: number of cans, vanity lights, GFCI outlets, exhaust fan upgrade, and any new circuits.
- Finishes: paint, trim, hardware, and whether you want a full repaint or touch-ups only.
- Who supplies what: confirm if you or the contractor buys fixtures, tile, and shower glass (model numbers help).
| Key decision | Why it changes the bid | What to do now |
|---|---|---|
| Move plumbing locations | More rough-in work, patching, and inspection coordination | Decide early if the layout truly needs it |
| Shower waterproofing system | Methods vary in materials, labor, and cure times | Ask bidders to specify the system in writing |
| Tile size/pattern | Large-format and complex patterns take more layout time | Pick a direction before you sign |
| Custom shower glass | Often requires templating after tile is complete | Build lead time into the schedule |
Small-Space Layouts That Make A Small Bathroom Feel Bigger
If you’re working with a tight footprint, a layout that improves clearances often delivers a bigger day-to-day upgrade than a pricey finish. These options also keep contractor bids easier to compare because they stay within typical framing and finish work.
- Shower swap in the same footprint: convert a tub to a shower while keeping drain and valve locations similar when possible.
- Door swing fix: switch to an out-swing or pocket-style door (when feasible) to free up vanity and toilet clearance.
- Storage without bulk: use a recessed medicine cabinet, shower niche, or shallow linen tower rather than deep cabinetry.
How To Compare Proposals (Without Getting Tricked By A Low Number)
- Ask for allowances to be clearly labeled (tile, fixtures, vanity) so you can judge realism.
- Look for line items that protect the build: waterproofing details, ventilation, and proper prep under tile.
- Confirm what’s excluded: painting scope, drywall repairs outside the bathroom, hauling, and debris fees.
- Make sure the contract spells out how change orders get priced and approved before work continues.

Permits, Inspections, And Local Requirements
In California, permit needs depend on the scope and the rules of your local city or county building department. For this reason, As a general guide, projects that change plumbing, electrical, ventilation, structural framing, or the waterproofed shower assembly often trigger permits and inspections.

- Will I get copies of approved plans/permits and the final sign-off when the job is complete?
- How do you handle corrections if an inspector calls something out?
