Removing a bathtub is a project that requires planning, patience, and physical effort. With the right tools and safety precautions, it can be a manageable job for the motivated do-it-yourselfer. This guide will walk you through the end-to-end process of bathtub removal to help you undertake this renovation project smoothly.
Introduction
Replacing an old or damaged bathtub can help refresh the look of your bathroom. Removing the existing bathtub is often the first and most labor-intensive step of the process. Depending on the type of bathtub you have, the removal process involves disconnecting the plumbing and cutting away or demolishing surrounding tile and fixtures before lifting out the tub.
Proper planning is key for a seamless bathtub removal. Assess the type of bathtub installation, gather the necessary tools and supplies, turn off water supply lines, and take safety precautions before starting demolition. This will help the project go smoothly and prevent costly damages.
Follow the steps in this guide to learn how to safely and effectively remove a bathtub in your bathroom remodel.
Assess the Bathtub Type
The first step is to assess what type of bathtub you have and how it is installed. This will determine the removal process. Common bathtub types include:
Freestanding Bathtubs
Freestanding tubs are not attached to the floor or walls. They have feet for support and flexible drain and supply connections. These are the easiest to remove.
Alcove Bathtubs
Alcove tubs fit between three walls and are usually attached to the surrounding tile. The plumbing connects through the walls rather than the floor.
Corner Bathtubs
Corner tubs fit into a corner of the bathroom. They may be surrounded by tile on two adjoining walls and require cutting into those surfaces for removal.
Drop-in Bathtubs
Drop-in tubs sit within a frame in the floor. The rim rests on the floor while the base hangs below. Removing involves demolishing the floor and cutting plumbing connections.
Undermount Bathtubs
Undermount tubs attach to the underside of the countertop edge. The surrounding tile extends down over the tub edges, so tile demolition is required.
Once you identify your type of tub, you can plan the appropriate removal process. Freestanding tubs are the simplest while alcove, corner, drop-in, and undermount tubs require more demolition.
Gather Tools and Materials
Bathtub removal requires an assortment of tools to disconnect and demolish fixtures. Having the right equipment on hand will make the job much easier. The basic toolkit for DIY bathtub removal includes:
- Hammer and chisel – for breaking up tile, plaster, etc.
- Pry bar – for pulling up stubborn tubs after demolition
- Reciprocating saw – for cutting tub material and plumbing pipes
- Safety gear – gloves, eye protection, mask, ear plugs
- Wheelbarrow and shovel – for hauling away debris
- Dust sheets – for protecting rest of bathroom from dust
- Wrenches – for disconnecting plumbing fixtures and valves
- Putty knife – for scraping away old caulk and adhesives
- Utility knife – for cutting away caulk, tile, etc.
- Flashlight – for looking into cramped plumbing spaces
- Bucket – for catching water from supply lines
- Plunger – for unclogging drains before removal
Also gather demolition supplies like a mini-sledgehammer, hacksaw, crowbar, and wood blocks. Have a shop vacuum ready to manage dust and debris. Rent any power tools needed like a jackhammer, rotary hammer drill, or tile cutter.
Shut Off Water Supply Lines
Before starting demolition, you need to shut off the water supply lines feeding the tub and shower. This prevents water from spurting out when you disconnect plumbing.
Locate the shut-off valves for the hot and cold supply lines. They are typically under the sink or behind an access panel. Turn the valves clockwise to shut off water flow.
Open the tub faucet to release pressure and drain any remaining water from the pipes. Check for leaks and tighten any connections if needed.
Place a bucket beneath the tub drain to catch any residual water still in the plumbing. Unscrew the drain cover plate and remove the drain plug. Having the lines drained will make disconnecting easier.
Remove Fixtures and Surrounding Materials
With the water supplies shut off, you can start removing fixtures attached to the tub. This includes:
- Showerhead, arm, valves, and plumbing
- Faucet fixtures, handles, spout, and supply lines
- Drain assembly and P-trap pipework
- Shower doors, rods, shelves and hardware
- Surrounding tile, drywall or plaster
- Caulk, adhesives, grout around the tub edges
Carefully detach each component. Climb into the empty tub to reach plumbing in the walls. Use recip saws and utility knives to cut away caulk and tile. Protect walls and floors from damage.
Remove shower wall surfaces as needed to access plumbing. Chip away tile or break up fiberglass enclosures. Consult a pro if unsure about removing structural material.
Pile debris into buckets and wheelbarrows. The more fixtures, tile and finishes you clear away, the easier it will be to remove the tub itself.
Disconnect and Cut Supply Lines
With the perimeter clear, you can start cutting away the tub’s water supply connections.
Place buckets beneath the supply lines. Use a mini-hacksaw to carefully cut through the pipes. Wear eye protection when pipes start draining.
For plastic pipes, a reciprocating saw works better than a hacksaw. Support the pipes as you cut to prevent cracking.
Once the hot and cold supplies are severed, detach the stub outs from the surround framing. Cap and seal the ends so water doesn’t leak into the wall cavity.
Plastic PEX and copper pipes are easiest to remove and replace. Consult a plumber if dealing with old galvanized steel supply lines.
Break Tub Away from Surround Materials
Next, break the tub free from surrounding flooring and construction materials. This takes force, so safety precautions are critical.
Wear thick gloves, eye and ear protection when demolishing. Make sure no one is in the room below in case debris comes crashing through the ceiling.
For tubs with skirts attached to walls, use a hammer and chisel to break away chunks of skirt material. Knock from the bottom upward and take care not to damage studs.
Use a pry bar inserted into the tub rim to gradually leverage the tub away from alcove walls and corner installations. Apply steady force.
For drop-in tubs, demolish the surrounding floor with a jackhammer or rotary hammer. Break up tile, concrete, or wood subfloor to free the tub base.
Lift and Remove Tub
Once fully detached, you can lift out the old tub for removal. This often requires two strong people, as cast iron and stone tubs can weigh several hundred pounds.
Slide a furniture dolly underneath the tub. Carefully tilt and roll the tub out of the alcove onto the dolly.
For awkward corner tubs, remove adjoining walls as needed to create a straight exit path. Pry tub loose slowly.
Some tubs can be lifted out whole after breaking surround materials. For large and heavy tubs, it is better to break the tub into manageable chunks for removal.
Use a hammer and chisel or reciprocating saw to break up fiberglass, acrylic, porcelain, or iron tubs. Wear a mask to avoid breathing shards and dust.
Place tub pieces into heavy duty garbage bags or wheelbarrows. Remove all debris from the premises. Now the tub cavity is clear and ready for the new bath installation.
Bathtub Removal FAQs
Removing a bathtub on your own takes grit and determination. Here are answers to some frequently asked questions:
How long does it take to remove a bathtub?
Plan for the project to take 2-3 days. Removal alone may take several hours depending on the installation. Preparation and cleanup adds more time.
Can I remove a tub in one piece?
Cast iron and stone tubs are extremely heavy, so breaking apart first is safest. Fiberglass and acrylic tubs can often be lifted out whole if not too large.
What tools do I need to remove a bathtub?
A hammer, chisel, pry bar, reciprocating saw, putty knife, wrenches, and safety gear are essential. Rent power tools for demolishing surrounds.
How do I dispose of an old bathtub?
Most waste management companies will haul away a tub for an added fee. Some scrap metal yards also take cast iron tubs.
Should I remove a bathtub myself?
If you are confident in your demolition skills, have time, and can handle the weight, DIY removal is achievable. Otherwise, hire a contractor.
What are bathtub sizes?
Standard sizes range from 60-72 inches long and 30-42 inches wide. Measure your old tub to get the dimensions for the new one.
Can I convert a tub into a walk-in shower?
Yes, this is a great option if you want an accessible shower rather than a tub. The conversion involves new plumbing and waterproofing.
How much does it cost to remove and replace a bathtub?
For DIY its $200-500 for tools and disposal. Hiring a plumber costs $1000-2000 including new tub installation.
Conclusion
Removing an old bathtub takes time and physical effort, but it is a manageable project for a committed DIYer. Follow safety precautions, use the proper tools, and demolish carefully to avoid damage.
The key steps are shutting off water supplies, detaching fixtures, cutting away surround materials, freeing the tub, demolishing if necessary, and hauling away debris. Expect the process to take 2-3 days.
With the old tub gone, you have an open canvas to remodel your dream bathroom. Take measurements and shop for the perfect new bathtub in the size, style and budget you desire. The hard work of removal will pay off when you relax in your fresh new tub.
