Quick Answer
Yes, it is possible to put a freestanding bathtub in a shower. Freestanding tubs are designed to stand on their own without being attached to the floor or walls. This makes them a versatile option that can be placed in a variety of locations, including inside a large walk-in shower. There are a few considerations when installing a freestanding tub in a shower:
- The shower needs to be large enough to comfortably accommodate the tub. Standard bathtubs are around 60 inches long, so the shower should have interior dimensions of at least 6 by 6 feet.
- The floor of the shower needs to be able to support the weight of a full tub, which can range from 100 to 200 pounds for cast iron and acrylic freestanding tubs.
- Proper drainage is important to keep water from pooling around the tub. The shower floor should slope towards the drain and the tub should have an overflow drain.
- Non-slip surfaces are essential for safety. The tub floor and shower floor should have a textured finish to prevent slipping.
- Adequate access to the shower and tub controls is necessary. There needs to be enough room to step in and out of the tub safely.
- The plumbing and electrical involved with installing a tub in a shower can be complex. Hiring professional installers is highly recommended.
With proper planning and installation, a freestanding tub can create a luxurious spa-like experience in a large walk-in shower. The open concept provides a seamless look and the convenience of bathing and showering all in one space.
Freestanding Tub Considerations
When selecting a freestanding tub to place in a shower, there are a few important factors to consider:
Size
Freestanding tubs come in a variety of shapes, sizes, and dimensions. Measure the interior size of your shower and purchase a tub that will fit comfortably within the space. Leave a minimum of 12 inches of clearance on all sides for easy access. Standard tubs are around 60 x 30 inches but larger and smaller sizes are available.
Weight
The full weight of a tub filled with water and bathers needs to be supported. Heavier materials like cast iron and stone require sturdy structural reinforcement. Lighter acrylic and fiberglass options weigh less. Consult a contractor to ensure the flooring can handle the load.
Material
Freestanding tubs are commonly made from:
- Acrylic – Affordable, lightweight, easy to clean, many color options
- Enameled cast iron – Durable, holds heat well, vintage look
- Fiberglass – Lightweight, budget-friendly, lower maintenance
- Copper – Beautiful but expensive, requires frequent polishing
- Wood – Looks stylish but higher maintenance to treat and seal
Consider the pros and cons of each when selecting a material that suits your space and needs.
Style
Freestanding tubs come in rectilinear, oval, round, and slipper styles. Choose a look that fits your bathroom aesthetic. Clawfoot tubs have a classic, vintage appeal. Modern styles feature clean lines and minimal ornamentation.
Features
Look for tubs with features like integrated overflow drains, textured bottoms, contoured headrests, armrests, and high-end faucets and fixtures. Consider options like air jets, vibration massage, and chromatherapy lighting.
Shower Design Considerations
The design of the shower must be well-suited for accommodating a freestanding tub. Here are some key factors to address:
Size
The shower must have interior dimensions large enough to hold the tub and allow sufficient surrounding space. Standard bathtubs are approximately 60 x 30 inches. The shower should have minimum interior dimensions of approximately 6 x 6 feet.
Layout
Consider the ideal placement for the tub within the shower. It should be easily accessible and have clearance around all sides. Make sure the layout allows for opening shower doors or curtains without obstruction.
Weight Capacity
Consult an architect or builder to ensure the shower floor structure can support the full weight of the tub when filled with water and people. This may involve reinforcement of the subfloor.
Waterproofing
It’s critical that the shower be fully waterproofed to prevent leaks and water damage. Cement backer board, liquid rubber membranes, and prefabricated bases can help.
Drainage
The shower floor must slope properly towards the drain to prevent water from pooling around the tub. A linear drain along the entire edge is ideal. The tub should also have an overflow drain.
Ventilation
Proper ventilation controls humidity and prevents mold and mildew growth. Exhaust fans, operable windows, and dehumidifiers can help.
Finishes
Use non-porous, natural stone or tile finishes that are low maintenance and slip resistant. Stay away from smooth surfaces that may become slippery when wet.
Accessibility
There should be sufficient clearance to safely step in and out of the tub. Install secure handrails if needed. Ensure easy access to the shower and tub controls.
How to Install a Freestanding Tub in a Shower
Installing a freestanding tub in a shower requires careful planning, the right tools and materials, and basic plumbing, electrical, and tiling skills. Here is an overview of the installation process:
Plan the Layout
Finalize the size and location of the tub within the shower based on the space and usage requirements. Ensure adequate access and clearance all around. Mark the footprint so walls, finishes, and fixtures can be oriented accordingly.
Waterproof the Shower
Thoroughly waterproof the shower pan, walls, and niche areas with a hot mop system, liquid membrane, or prefabricated sub-base. This prevents leaks and water damage. Slope the floor 1/4 inch per foot towards the drain.
Reinforce the Floor
Add structural support beneath the shower floor to handle the weight of the full tub. This may involve adding a mortar bed, cement backer board, or reinforcing the subfloor.
Install Plumbing
Rough in new drain and supply lines. Connect the tub’s drain outlet to the shower drain. Install shutoff valves. Run piping for the faucet and any special features.
Install Walls and Panels
Erect the shower framing and cement backer board around the planned tub location. Use silicone to seal seams and joints. Apply waterproofing over the boards.
Tile the Surfaces
Apply your desired tile, stone, or other finish to the shower walls, floors, and niches. Use materials that are low maintenance and slip resistant.
Install the Tub
Place the freestanding tub in the planned location and adjust to ensure it is level. Connect the drain outlet and overflow. Seal with caulk.
Complete the Fixtures
Install the tub faucet, showerheads, valves, and other fixtures. Make sure to seal connections with silicone. Attach shower doors or curtains.
Test for Leaks
Thoroughly test shower and tub operation. Check for leaks around connections and seals. Verify proper drainage. Make any final adjustments.
