5 Tips to Consider Before Remodeling a Bathroom

How much should you budget for a bathroom remodel?

Budget by the size of the room and the finish level. Our published starting prices run from $25,000+ for a small bathroom on Basic to $225,000+ for a Super-Luxury primary bath, each with a standard material allowance. The full breakdown is in Cost of a Bathroom Remodel in the Greater Seattle Area.

Starting prices leave out permit fees, rot or water damage found at demolition and upgrades beyond the allowance. Moving a drain is extra on small and medium rooms, and below Super-Luxury on large and primary rooms. We price these in writing when a project needs them.

Our past jobs show the scale. A Bellevue walk-in shower bathroom cost about $35,000 in 2024. A Kirkland condo project, a tub to walk-in shower conversion plus a second bathroom, cost about $40,000 in 2023. A Kirkland charcoal tile shower bathroom cost about $55,000 in 2024. Those are the prices of the year each room was finished. Material and labor costs have risen since, which is why today's starting prices are higher.

Should you keep the bathroom layout or move the toilet and shower?

Keep the layout if the room works. Leaving the toilet, vanity and shower on their existing drains saves the most money. Every move means new pipe under the floor, opened walls and new venting.

Move things when the room does not work. Stand in the doorway: if the toilet is the first thing you see from the hall, price moving it out of that line of sight, or closing it off with a sliding door. In a primary suite, a separate toilet room is one of the common layouts.

Decide early about the tub. In a Kirkland condo in 2023, we removed a corner soaking tub and a small shower stall and built one large walk-in shower in their place. If a tub is the only one in the house, we talk that choice through with you first. In a Redmond master bathroom with a navy vanity, the old jetted tub no longer worked. It gave way to a larger walk-in shower and a freestanding soaking tub. If a jetted tub is on your list, read How Much Does a Jacuzzi Bath Remodel Cost?

Does a bathroom remodel need a permit, and how long does it take?

A permit is usually needed when plumbing, electrical or walls change. The 2021 Seattle Residential Code (R105.2 item 2) exempts surface finishes over existing wall and ceiling systems from a building permit when the building envelope does not change. Moving plumbing needs a plumbing permit, and moving wiring needs an electrical permit. In Seattle, the building and electrical permits come from the Seattle Department of Construction and Inspections, and the plumbing permit from Public Health, Seattle and King County. A Bellevue bathroom goes through Bellevue Development Services. For the full rules, read Do you need a permit to remodel in Seattle?

Time on site depends on the size of the room. Design, selections and permits come before it. Our Kirkland condo bathroom took about 13 weeks, from demolition in mid March 2023 to completion on June 14, with the plumbing and electrical roughed in under a permit issued April 4. A Redmond master bathroom with an open walk-in shower took about 18 weeks of construction in 2023.

Which bathroom finishes and lighting should you decide before demolition?

Decide tile, fixtures and glass before demolition. A change after the glass is measured or the tile is ordered costs time and money, and frameless glass and slab stone are measured after the tile is set. Changes can still be made by written change order. In that Redmond navy vanity bathroom, a shower bench, new ceiling drywall and a new exhaust fan were added that way, each priced before it was built.

Spend where it shows. A bathroom is small, so one better material changes the whole room. Vanity, counter, faucets, lighting and glass come in grades, and you can trade one up and another down. Our pricing guide says the same: choose Mid-Range finishes where they show.

Plan the lighting with the layout, because the wiring goes in before the walls are closed. Layer it: ceiling light for the room, task light at the mirror and an accent such as a lit niche. For a small bathroom, our Luxury level lists layered lighting and Mid-Range a simple lighting plan.

Collect photos of bathrooms you like, from saved boards online or a friend's shower, and bring them to the design meeting. Our designer turns them into tile, fixture and vanity choices and shows you the room in 3D before you approve it.

How do you choose a bathroom remodeling contractor?

Check the registration first. A general contractor working in Washington should be verifiable on the state Department of Labor and Industries site, with a surety bond and general liability insurance. Then compare itemized written quotes for the same scope, not headline prices. How to Find and Hire a Good Remodeling Contractor covers the checks in order.

A bathroom packs plumbing, electrical, tile, glass and cabinetry into a few square feet. When each trade is hired separately, nobody owns the schedule. Ask who runs the job day to day, who files the permits and who books the inspections.

We run every trade in the room under one contract and one project manager, file the permits and give you a written, line by line price before work starts.
