There’s a right order to a bathroom remodel, and it isn’t the order most people want. The parts you actually picked out — the tile, the vanity, the fixtures, the paint — go in last. The work that decides whether any of it lasts happens first, behind the walls and under the floor.
Get the sequence right and a typical bathroom takes about three to five weeks. Get it backward, and you’ll pay to tear out finished work the day the plumbing or the permit forces a change. Here’s the order a Middle Tennessee bathroom remodel should follow, and why each phase has to wait its turn.
Start With Design and Selections, Not a Sledgehammer
Every bathroom remodel starts on paper. Before anyone opens a wall, the layout gets set, the plumbing plan gets drawn, and every finish gets chosen and ordered. That last step is where projects quietly fall apart. A back-ordered tile or a vanity with a six-week lead time can freeze a job that’s otherwise ready to run.
We settle selections in the showroom before demo day for exactly that reason. Picking the tub, the tile, the vanity, and the faucets up front lets the whole schedule form around real lead times instead of hopeful guesses. It also locks the plumbing plan, because where the water lines run depends on the fixtures you chose.
Change your mind about a freestanding tub in week three and you’ve moved a drain that was already set.
This is also when you decide how the work gets run. A design-build remodeler carries the design, the permits, and the construction under one roof, so the plan that leaves the showroom is the plan that gets built. If you’re mapping out a full bathtub and shower remodel, the design phase is where the budget and the timeline actually get decided. Demo day just makes it official.
Permits and Rough-In Come Before Anything Pretty
Once the old bathroom is out, the next phase is the one nobody photographs: permits, plumbing, and electrical rough-in. This is where the project earns its timeline, and it’s the part homeowners are most tempted to rush.
In Metro Nashville, interior renovations run through the Department of Codes and Building Safety, and the permit is what triggers the inspections that let plumbing and electrical work move forward. Pulling it isn’t a delay you dodge by skipping. It just shoves the delay to the worst possible moment, after the walls are closed and the tile is up.
Rough-in is when the supply lines and drains get moved or added and the new wiring goes in, all while the framing is still open. In older Middle Tennessee homes, this is where the surprises live. Open a wall in a 1960s ranch and you might find galvanized supply lines or a drain that sits nowhere near the new plan.
Better to find that now, with the studs exposed, than after a tile setter has spent two days on the shower.
This phase also sets what you can’t easily change again. Moving a toilet drain or relocating a shower is routine while the wall is open and expensive once it’s tiled shut. Those are the calls that get locked in once the walls close up, so they belong in the plan, not in a mid-project change of heart.
One more thing gets decided here: who’s legally allowed to do the work. Tennessee requires a licensed contractor for any project of $25,000 or more, and the trades pulling plumbing and electrical permits carry their own licenses. On a full bathroom remodel, that threshold is easy to cross, so it’s worth confirming before anyone starts.
Waterproofing and Surfaces Set the Base
With rough-in inspected and signed off, the room gets closed up and waterproofed. This is the quiet phase that decides whether a bathroom lasts twenty years or starts leaking in three. Cement backer board or a waterproof membrane goes in around the tub and shower. Then tile. Then flooring.
Order matters inside this phase too. Wall tile usually goes up before the floor is finished, and the shower pan gets waterproofed and flood-tested before a single tile touches it. Rush the pan to keep the schedule moving and you’re setting up a leak behind finished tile. There’s no shortcut here that survives contact with water. Skip the flood test and you won’t know until the ceiling below turns brown.
Fixtures and Finishes Go in Last
Now the parts you chose finally get installed: the tub or shower, the vanity, the toilet, the lights. Finishes go last because each one sits on top of finished walls and floors. Hang a vanity before the flooring is down and you’ve either trapped it or left a gap you’ll stare at every morning.
The tub-versus-shower question shows up here in physical form, even though you settled it back in design. If you’re weighing whether to give up your last tub for a walk-in shower, that call had to be made before rough-in, because the drain and the framing differ. By the time fixtures arrive, the room is just following orders the plan gave weeks earlier.
What You Handle and What Your Remodeler Handles
A remodel feels less chaotic when everyone knows their lane. Most of the heavy lifting sits with the remodeler. Your part is smaller, but it matters more than you’d think.
You own the decisions and the daily logistics:
- Choosing finishes and signing off on the layout before demo starts
- Clearing the room and planning where you’ll wash up while yours is down
- Answering quickly when a surprise turns up behind a wall
Your remodeler owns the rest:
- Pulling permits and scheduling every inspection
- Sequencing the plumber, the electrician, and the tile setter in the right order
- Protecting the rest of your home from construction dust
- Keeping the site safe and the schedule honest
The single most useful thing you can do is decide early and hold that decision. A finish swap during rough-in ripples through the whole schedule. If you’d rather not manage that sequence at all, that’s the point of hiring it out. You can map out your remodel with our design team and let the order become our job, not yours.
How Long a Bathroom Remodel Takes and What It Costs
A quick recap for the skimmers. A standard Middle Tennessee bathroom remodel runs about three to five weeks of active work, longer for a full gut or a layout change that moves plumbing. Rough-in and inspection is the phase most likely to add days, because it leans on the codes office and on whatever the walls are hiding.
Cost swings even wider than the calendar, and scope drives it more than square footage. Moving plumbing, jumping to a custom shower, and choosing high-end tile are the levers that move a budget most. For a grounded look at what actually drives a bathroom remodel’s price, it helps to see where the money goes before you fix a number in your head.
The order protects both numbers. A remodel that runs in sequence rarely blows its timeline or its budget on rework. One that jumps ahead almost always does.
Ready to Plan Your Bathroom Remodel?
The order isn’t complicated once you see it: design and selections, then permits and rough-in, then waterproofing and surfaces, then fixtures and finishes. Getting it right is mostly about deciding early and letting each phase finish before the next one starts. That’s the part a good remodeler carries so you don’t have to.

Frequently Asked Questions
Can I stay in my house during a bathroom remodel?
Usually, yes, as long as you have a second bathroom. Crews work during the day and shut the water off only for short stretches. The hardest weeks are rough-in and tile, when the room is fully out of service. If it’s your only bathroom, plan where you’ll wash up before demo starts.
Do I really need a permit for a small bathroom remodel?
If you’re moving plumbing, changing wiring, or altering the layout, yes. Metro Nashville requires a permit for that work, and the permit triggers the inspections that protect you later. Swapping a faucet or repainting doesn’t. When in doubt, your contractor pulls the permit as part of the job.
Can I change my finish selections after work starts?
You can, but it’s the most expensive habit in remodeling. A tile or vanity change mid-project can stall the schedule and add cost, because later phases were ordered around your first choice. Settle selections before demo, and treat the plan as locked once the walls open.
Which part of the order causes the most problems if it’s rushed?
Waterproofing the shower. It’s invisible once the tile goes up, so a rushed pan or a skipped membrane test won’t show until water finds the gap months later. Fixing it means tearing out finished tile. No phase punishes a shortcut harder.
