How to Plan a Bathroom Remodel: Step-by-Step Guide

Why Bathroom Remodel Planning Matters

A bathroom remodel is one of the most worthwhile investments you can make in your home — but because a bathroom is small, plumbing-heavy, and constantly wet, it's also one where planning makes or breaks the result. Skip the planning and you risk water damage, layout regrets, and blown budgets. Get the planning right and you end up with a bathroom that's beautiful, watertight, and a pleasure to use for years.

This step-by-step guide walks through the planning process we use with homeowners across Marysville, Lake Stevens, Everett, Bothell, and the greater Seattle area. It covers layout, the shower decision, waterproofing, fixtures, budget, and timeline — so you know what to expect before demolition begins.

Step 1: Define What Isn't Working

Before you look at a single tile sample, get clear on why you're remodeling. Is the layout cramped? Is there visible water damage or a soft floor? Are you fighting for counter space every morning? Is the tub never used and you'd rather have a walk-in shower? Writing down your specific frustrations gives the remodel a clear goal and keeps later decisions anchored in what actually matters to you.

If you're planning to stay in the home long-term, that changes the plan too. A curbless walk-in shower, comfort-height toilet, and grab-bar-ready blocking in the walls are small additions during a remodel that make a bathroom safer and easier to age into — and they're much harder to add later.

Step 2: Decide on the Layout

The biggest cost variable in a bathroom remodel is whether the layout changes. Keeping fixtures in place means plumbing stays where it is; moving the toilet, sink, or shower means rerouting supply and drain lines, which adds cost quickly. Sometimes a layout change is absolutely worth it — a poorly placed toilet can make a small bathroom feel smaller — but make that decision with eyes open.

Tub-to-shower conversions are one of the projects we do most often, and for good reason: most people don't use a tub every day, and a walk-in shower makes the room feel larger and more modern. We build them with proper waterproofing behind the tile so they stay leak-free.

• Keep the toilet, sink, and shower where they are to save on plumbing costs
• Moving the toilet is the most expensive change — it means rerouting the drain
• A tub-to-shower conversion is one of the most requested and impactful changes
• A double vanity needs enough wall space and a clear walkway in front
• Leave at least 30 inches of clearance in front of the toilet and shower

Step 3: Plan the Shower — Tiled, Walk-In, or Curbless

A custom tiled shower is the centerpiece of most of the bathrooms we build. We construct walk-in and curbless showers with a properly waterproofed pan and membrane behind the tile, so they look great and stay watertight for years. Curbless designs are especially worth considering if you plan to stay in the home — there's no step to trip over, and they make a small bathroom feel larger.

Waterproofing is the part you'll never see but the part that matters most. A beautiful tile job over bad waterproofing will eventually leak and rot the framing and subfloor. We waterproof first and tile second, and we don't cover anything up before the waterproofing is right.

Step 4: Choose Vanities, Countertops, and Fixtures

A vanity sets the storage tone for the room. Semi-custom cabinetry gives you the drawer and door configurations you want without full custom pricing. Quartz countertops are our most common choice for vanities — they're non-porous, stain-resistant, and available in a wide range of looks. A single-piece vanity top with an integrated sink cuts down on seams where water can sneak in.

For fixtures, we install Moen, Delta, and Kohler because they're reliable and well-supported. Pick your faucet, shower valve, and showerhead early — the rough-in plumbing depends on which brand and model you choose, so the selection has to happen before the walls close up.

Step 5: Don't Forget Ventilation, Lighting, and Flooring

A bathroom without good ventilation grows mold. If your current fan is weak or missing, plan to add a properly sized fan vented to the outside — not into the attic. Good lighting layers overhead, vanity, and shower light so you can see for makeup in the morning and wind down at night. We plan the electrical layout before rough-in so the lighting lands where it should.

For flooring, tile and luxury vinyl plank both handle a bathroom's wet environment well. Tile is classic and can run up the shower wall for a cohesive look; luxury vinyl plank is warmer underfoot and more forgiving if something gets dropped. We install both.

Step 6: Set a Realistic Budget

Most of our full bathroom remodels fall between $15,000 and $35,000. A simple refresh — new vanity, fixtures, toilet, and flooring in the same layout — sits at the lower end. A full gut with a custom tiled walk-in shower, moved plumbing, and new lighting sits at the higher end. The tile and fixtures you choose, whether plumbing moves, and what we find behind the walls all affect where you land.

Be honest with your contractor about your budget. A good contractor will show you where to invest for the biggest impact and where you can save, and they'll give you a written, fixed-price quote so there are no surprise line items. That's exactly how we quote.

Step 7: Understand the Timeline

Most bathroom remodels take 2 to 4 weeks from demolition to completion. The shower build — waterproofing, pan, tile, and grout — is the longest single piece, and it can't be rushed or the waterproofing won't cure properly. We give you a realistic schedule with your quote and keep you updated if anything changes.

If it's your only bathroom, talk through a plan before demolition starts. Some homeowners stay elsewhere for the messiest stretch; others make do with a half-bath or a temporary setup. We contain the work area and clean up daily to keep the rest of the house livable.

Step 8: Plan for What's Behind the Walls

Older bathrooms around the Pacific Northwest frequently hide water damage or rot behind the tile and under the floor — it comes with the territory of a wet climate and decades of moisture. When we open the walls, we inspect and repair any rot we find before we cover it back up. We'll show you what we found, explain the fix, and price any extra work in writing before doing it. Fixing the rot now is far cheaper than fixing it after a new bathroom is built over the top of it.
