- Professional waterproof sealing

A professionally installed bathtub not only looks better but also performs reliably for years.
Choosing the Right Bathtub
Before installation begins, selecting the right bathtub is essential. Different bathroom layouts require different bathtub styles.
Popular bathtub options include:
- Freestanding bathtubs
- Alcove bathtubs
- Corner bathtubs
- Built-in bathtubs
- Walk-in bathtubs
- Acrylic bathtubs
- Steel and cast iron bathtubs
The ideal choice depends on your available space, budget, and design preferences.
The Bathtub Installation Process
Professional bathtub installation involves much more than simply placing a tub into position.
- Removing the Existing Bathtub
If replacing an old bathtub, installers safely disconnect plumbing, remove the existing fixture, and inspect the floor and walls for hidden damage.
- Preparing the Installation Area
The floor is checked for levelness and structural integrity. Plumbing connections are inspected and adjusted if necessary before the new bathtub is positioned.
- Fixing Bathtub Underneath
One of the most important steps is fixing bathtub underneath properly. The bathtub must be securely supported to prevent movement, flexing, or cracking over time.
Professional installers use appropriate support frames, adjustable legs, or mortar beds depending on the bathtub type. This ensures the weight is distributed evenly and prevents unnecessary stress on the bathtub base.
Poor support underneath is one of the leading causes of bathtub movement and plumbing failures.

Plumbing Connections
Once the bathtub is securely fixed, all plumbing components are connected.
This includes:
- Waste pipe installation
- Overflow connection
- Drain fitting
- Water supply inspection
- Leak testing
Every joint is carefully tested before finishing work begins.
Applying Sealant Around Bathtub
Applying high-quality sealant around bathtub is essential for preventing water damage.
Professional bathroom-grade silicone creates a waterproof barrier between the bathtub and surrounding walls.
Benefits of proper sealing include:
- Prevents water penetration
- Reduces mold and mildew growth
- Improves bathroom hygiene
- Creates a clean, finished appearance
- Extends the lifespan of bathroom surfaces
Old or damaged sealant should be removed completely before applying a fresh waterproof seal.
Common Bathtub Installation Mistakes
DIY bathtub installations often result in expensive problems later.
Some common mistakes include:
- Incorrect plumbing alignment
- Uneven bathtub positioning
- Poor drainage slope
- Inadequate support underneath
- Low-quality silicone sealant
- Failure to waterproof surrounding walls
Professional installation helps eliminate these risks.
How Long Does Bathtub Installation Take?
Most standard bathtub installations can be completed within one day.
However, larger renovation projects may require additional time if they involve:
- New plumbing
- Tile replacement
- Floor repairs
- Waterproofing work
- Custom bathtub installations
Your installer should provide a clear timeline before work begins.

Frequently Asked Questions
- How much does bathtub installation in London cost?
The cost depends on the bathtub type, plumbing requirements, and whether the existing bathtub needs to be removed. A professional inspection provides the most accurate estimate.

Proper support underneath prevents movement, cracking, uneven weight distribution, and future plumbing issues, significantly extending the bathtub’s lifespan.
- How often should the sealant around bathtub be replaced?
Bathroom silicone sealant typically lasts between 5 and 10 years, depending on usage and moisture levels. It should be replaced if it becomes cracked, moldy, or starts separating from the surfaces.
