Bathroom Remodel Cost in Knoxville: 2026 Guide by Size and Scope

Your bathroom remodel cost depends mostly on two things: how big the room is and how much you change. A quick refresh with paint and new fixtures costs far less than tearing the room down to the studs. Knowing the typical numbers before you call anyone helps you set a budget that fits your home and your plans.

Quick answer: Nationally, the average bathroom remodel cost is about $15,586, according to This Old House. Most homeowners pay between $6,456 and $24,715. A small refresh sits at the low end, while a large primary bath with new tile and plumbing lands at the high end.

These are national figures, not local quotes. Prices in East Tennessee vary with your home, your choices and what is hiding behind the walls. This guide covers cost by size, scope and part, what pushes the price up, and how to save. When you want a real number, our bathroom remodeling team can give you a free in-home estimate.

Average Bathroom Remodel Cost in 2026

This Old House surveyed homeowners and studied project costs to find a national average of $15,586. That number covers a wide mix of jobs, from quick updates to full gut remodels. The typical range runs from $6,456 to $24,715. A few large, high-end projects cost more than that.

Two more numbers help frame it. A full remodel, which includes demolition and hauling away the old materials, averages $18,706 for rooms from 40 to 150 square feet. A cosmetic remodel without demolition averages about $11,582. Cosmetic work means new paint, fixtures, a vanity or lighting, while the walls and plumbing stay where they are.

Bathroom Remodel Cost by Size

Size matters because a bigger room needs more tile, more flooring, more drywall and more hours of labor. Here are the national ranges by square footage from This Old House:

• Small bath (40 to 60 sq ft): $12,695 to $14,845
• Standard hall bath (70 to 90 sq ft): $15,920 to $18,070
• Large bath (100 to 120 sq ft): $19,166 to $21,295
• Primary suite (130+ sq ft): $22,370 to $24,715

Many older ranch homes around Knoxville have a hall bath in the 40 to 60 square foot range. Newer homes in places like Farragut often have larger primary baths with a separate tub and shower. Measure your room, then use the matching range as a rough starting point. It is not a quote, but it tells you what ballpark you are in.

Bathroom Remodel Cost by Scope

Scope means how much of the room you change. The more you replace, move or upgrade, the higher the price. For a 50 square foot bathroom, This Old House breaks the national cost to remodel a bathroom into three levels. Each one fits a different goal and budget, so think about what problem you want to solve first.

Basic Refresh: $8,478 to $10,883

A basic refresh keeps the layout. You might swap the vanity, toilet, faucet, lights and mirror, then paint and put down new flooring. It works well when the tub and plumbing are in good shape and you just want the room to look current. It is also the fastest option, so you are without your bathroom for less time.

Midrange Remodel: $14,609 to $19,040

A midrange job usually adds a new tub or shower, new tile and better fixtures. You may also get a vanity with more storage and a better exhaust fan. This is where many families land when the old bath is worn out, leaks or just does not work for them anymore. The layout often stays the same to keep plumbing costs down.

High-End Remodel: $27,492 to $35,808

High-end projects often move walls or plumbing. They may add a large tile shower with glass, heated floors, custom cabinets and stone counters. Each of those choices adds cost on its own. Together they push the price well past the national average. If you want this level, plan extra time for design and for ordering materials.

Which Parts of a Bathroom Remodel Cost the Most?

It helps to see where the money goes. This Old House lists these average national costs for common parts of a bathroom job:

• Complete shower remodel: $8,044
• Plumbing: $5,545
• Cabinetry, including removal: $2,929
• Insulation and drywall: $2,338
• Water heating upgrade: $1,478
• Tiling: $1,326
• Tub-and-shower combo: $1,258
• Painting: $1,145
• Freestanding tub: $1,123
• Flooring: $1,114
• Toilet, installed: $467
• Electrical: $456
• Bathtub faucets: $423
• Countertops: $332
• Electrician labor: $40 to $120 per hour

The shower and the plumbing are the two biggest line items. That is why moving a toilet or shower drain to a new spot can raise your bathroom remodel cost so fast. Keeping fixtures where they are is one of the easiest ways to stay on budget. If a new shower is your main goal, our walk-in shower cost guide covers that one piece in more detail.

What Drives Your Bathroom Remodel Cost Up or Down

Two bathrooms the same size can have very different prices. These are the factors that usually make the biggest difference:

1. Layout changes. Moving a toilet, shower or sink means new drain and supply lines. Plumbing is already one of the largest costs.
2. Materials. Natural stone, large tile, quartz counters and custom cabinets cost more than stock options.
3. Shower type. A custom tile shower takes more labor than an acrylic shower system.
4. Hidden damage. Rotted subfloor, mold or old wiring found during demolition has to be fixed before new work goes in.
5. Access. Tight spaces, a second-floor bath or a low crawl space can add labor time.
6. Electrical and ventilation. New lights, safe outlets near water and a fan vented outside add cost, but they protect your home.

Hidden damage is the one factor you cannot plan for exactly. That is why it makes sense to keep a cushion in your budget, which we cover below.

East Tennessee Notes on Bathroom Remodel Cost

Our humid summers are hard on bathrooms. Steam has nowhere to go if the exhaust fan is weak or vents into the attic instead of outside. Over time that moisture can lead to peeling paint, soft drywall and mold. The EPA’s guide to mold and moisture explains why controlling damp air matters. A good fan, vented the right way, is a small cost that protects the rest of the room.

Many homes in Knox County, Blount County and Anderson County were built decades ago. Older baths may have galvanized pipes, outdated wiring or subfloors softened by years of small leaks. Homes on crawl spaces and sloped lots can take extra work to reach the plumbing. None of this is unusual, but it can add to the bathroom remodel cost once the walls are open. Cabins and rentals in Sevier County often need tough, easy-clean finishes that stand up to heavy use.

How to Budget for Your Bathroom Remodel Cost

Start with the size and scope ranges above to pick a rough target. Then rank what matters most to you, such as a bigger shower, more storage or easier cleaning. Spend on the things you use every day and save on the rest. For a quick ballpark, try our home remodeling cost calculator, then book a visit for a real number.

Keep a cushion in your budget for surprises, like a rotted subfloor or a pipe that needs replacing. A good contractor will point out what they can see before work starts, but nobody can see through tile. A cushion means a surprise does not stall your project or force you to cut a feature you really wanted.

Ways to Save on a Bathroom Remodel

Saving money does not have to mean a bathroom you do not like. These choices often lower the price without hurting the result:

• Keep the toilet, sink and shower in the same spots.
• Choose an acrylic bath or shower system instead of custom tile. American Home is an authorized Bath Planet dealer, and these systems have far fewer grout lines to scrub.
• Pick a stock vanity and mid-priced tile, then spend a little more on fixtures you touch every day.
• Fix small leaks early so the damage does not spread to the floor or walls.
• Do related work at the same time so you only open the room once.

Financing Your Bathroom Remodel

You do not have to pay for everything up front. American Home offers $0 down financing options for qualified homeowners. That can let you fix a leaking shower now instead of waiting and risking more damage. Ask about financing during your estimate so you can compare a monthly plan with paying cash. Read the terms carefully before you sign, and pick a plan that fits your monthly budget.

How Long Does a Bathroom Remodel Take?

In the This Old House survey, nearly two-thirds of homeowners said their remodel took one to four weeks. About 1 in 5 said it took longer than a month. A basic refresh sits at the short end. A full gut job with new tile, plumbing and custom parts takes longer.

Ordering materials can add time before work even starts, especially for custom vanities or special tile. If you have only one bathroom, ask how long you will be without a working toilet or shower. A good contractor plans the work in an order that keeps that time as short as possible.

Mistakes to Avoid and Questions to Ask a Contractor

A few common mistakes raise the bathroom remodel cost or lead to regret later:

• Picking the lowest bid without checking what it includes.
• Skipping the exhaust fan or venting it into the attic.
• Choosing finishes before you settle on the layout.
• Starting work without a written price and scope.

Before you hire anyone, ask these questions:

• Is the price in writing, and what exactly does it include?
• Who handles permits and inspections?
• What happens if you find damage behind the walls?
• How long will I be without a working bathroom?
• Are you licensed and insured in Tennessee?
