A bathtub remodel can transform a tired bathroom, improve safety, and add value to your home, but costs and choices vary widely. A simple tub replacement may cost a few thousand, while a full bathroom remodel with new plumbing, tiling, and fixtures can cost much more. Understanding the options before you start helps you set a realistic budget and avoid expensive changes mid-project.
This guide explains typical bathtub remodel costs, popular ideas for different budgets, and a step-by-step process from planning to finishing. It also covers permits, timelines, and mistakes to avoid.
How Much Does a Bathtub Remodel Cost?
Costs depend on the scope, materials, and labour in your area. A basic replacement, where a new tub fits the existing plumbing and alcove, is usually the cheapest option. A mid-range remodel, with a new tub, surround, taps, and tiling, costs more. A high-end remodel, with a freestanding tub, moved plumbing, custom tiling, and new flooring, is the most expensive.
Labour is often a large part of the cost, especially if plumbing or walls need to move. Always get at least three quotes, ask what is included, and allow a contingency of 10 to 20 percent for hidden problems such as water damage or old plumbing that needs replacing.
| Remodel level | Typical scope | Indicative cost range |
|---|---|---|
| Basic replacement | Same size tub, same plumbing | Lowest, a few thousand |
| Mid-range update | New tub, surround, taps, tiling | Moderate, several thousand |
| Full remodel | New tub, moved plumbing, new floor and walls | Highest, ten thousand or more |
These ranges are indicative only and vary by region, materials, and contractor. Get local quotes for an accurate budget for your project.
Remodel Ideas for Every Budget
Budget-Friendly Ideas
For a low budget, keep the plumbing in place, refinish rather than replace where possible, and focus on a new tub surround, taps, and paint. A new shower curtain or screen, updated lighting, and a fresh sealant can make an old tub look much better without a full remodel. Small changes to grout and caulk also improve hygiene and appearance quickly.
Mid-Range Ideas
For a mid-range budget, replace the tub with a modern acrylic or steel model, add a tiled surround, and upgrade taps and shower fittings. Consider a deeper soaking tub if space allows, and add a niche for toiletries. Good lighting, a heated towel rail, and anti-slip flooring improve comfort and safety without moving plumbing.
High-End Ideas
For a larger budget, consider a freestanding tub as a focal point, a walk-in shower alongside the tub, underfloor heating, and custom tiling. A freestanding tub needs floor plumbing and space around it for cleaning, so check those details early. Natural stone, wood-effect tiles, and frameless glass can create a spa-like feel, but they need careful waterproofing.

Step-by-Step Bathtub Remodel Guide
Step 1: Plan and Measure
Measure the bathroom, note plumbing positions, and decide whether you will keep the layout or move plumbing. Choose a tub type and size, and check door clearance, floor strength, and water heater capacity. Get a clear brief for contractors, including materials, finishes, and a timeline.
Step 2: Set a Budget and Get Quotes
List all costs: tub, surround, taps, tiling, flooring, labour, disposal, and permits if needed. Get at least three written quotes, compare what is included, and check references and insurance. Agree a payment schedule tied to completed work, not just dates.
Step 3: Order Materials and Prepare
Order the tub and fittings early, because lead times can delay work. Protect other rooms from dust, plan for a bathroom you can use during the work, and confirm delivery access. Check that the tub fits through doors and hallways before demolition starts.
Step 4: Demolition and Rough-In
Remove the old tub, surround, and damaged materials carefully, and check for leaks, mould, or rot underneath. Plumbers and electricians then move or update pipes and wiring, and walls are prepared for waterproofing. This is the stage where hidden problems appear, so keep your contingency budget available.
Step 5: Install, Tile, and Finish
Install the new tub, level it, and connect plumbing. Waterproof the surround, tile walls and floors, fit taps and shower fittings, and seal all joints. Finally, paint, fit accessories, and clean thoroughly. Test all taps, drains, and showers before final payment, and keep warranties and care instructions.
How Long Does a Bathtub Remodel Take?
A simple replacement can take two to five days. A mid-range remodel usually takes one to two weeks, including tiling and drying time. A full remodel with moved plumbing can take three to six weeks, depending on contractor availability and material lead times. Plan for disruption, and do not schedule a remodel just before guests arrive or a holiday.
Common Mistakes to Avoid
Do not choose a tub before measuring doorways and plumbing, do not skip waterproofing to save money, and do not start demolition before materials arrive. Also check local permit rules: moving plumbing or electrical work often needs approval and inspection. Finally, keep all warranties, and do not pay in full until you have tested the tub, checked seals, and confirmed that tiling and finishes are complete.
Frequently Asked Questions
How much does a bathtub remodel cost?
A basic replacement can cost a few thousand, a mid-range remodel several thousand, and a full remodel ten thousand or more, depending on materials, plumbing changes, and local labour costs. Get at least three local quotes for an accurate figure.
Can I remodel a bathtub without moving plumbing?
Yes, and it is usually much cheaper. Keeping the tub in the same place and using the existing drain and supply lines avoids major plumbing work. Moving plumbing adds cost, time, and often permit requirements.

A simple replacement takes two to five days, a mid-range remodel one to two weeks, and a full remodel three to six weeks, depending on scope, materials, and contractor availability.
Is it better to refinish or replace a bathtub?
Refinishing is cheaper and faster if the tub structure is sound but the surface is worn. Replacement is better if the tub is cracked, badly stained, the wrong size, or you want a different style or accessibility features.
Do I need a permit for a bathtub remodel?
It depends on your location and scope. Simple like-for-like replacements often do not need a permit, while moving plumbing, electrical work, or structural changes usually do. Check with your local authority or contractor before starting.
The Bottom Line
A successful bathtub remodel starts with clear planning, a realistic budget, and a tub that fits your space and plumbing. Keep the layout where possible to control costs, invest in waterproofing and quality fittings, and get written quotes before work begins. With those steps, your new bathtub can improve daily comfort, safety, and the value of your home for many years to come.
