Drain and Water Line Reversal Is Common

Many homeowners worry that the drain side or water supply location will prevent a walk-in
tub from fitting properly. In reality, reversing the drain and water supply lines is often
very straightforward with a walk-in bathtub installation.

Most walk-in bathtubs are designed with open access underneath the frame, allowing plumbing
to be routed beneath the tub when needed.

This is a very common installation practice and is often done to ensure the walk-in tub door
is not blocked by obstacles such as:

• Toilets
• Vanities
• Bathroom doors
• Tight wall layouts
• Limited transfer space

Reversing the plumbing layout may allow the door to swing or position more comfortably for
the person using the tub.

Text Bathroom Pictures for Help

The easiest way to get guidance before ordering is to text pictures of your bathroom to
WalkInTubUSA.

Photos help identify:

• Drain side orientation
• Potential door clearance issues
• Toilet and vanity interference
• Wall surround condition
• Possible plumbing modifications
• Accessibility concerns

Wall Surround Installation Tips

Walk-in bathtubs are designed to install against either:

• Existing wall tile
• New wall surround systems
• Stone slab wall systems

In many installations, it is cleaner and more efficient to complete the wall preparation
and wall surround work before the new tub is fully set into place.

This helps:

• Create neater finish work
• Reduce awkward wall access
• Improve waterproofing detail
• Speed up installation efficiency

WalkInTubUSA also offers stone slab wall systems available in approximately 40 colors that
can ship together with your walk-in bathtub order.

Securing the Tub Properly

A properly installed walk-in bathtub should feel solid and stable.

Most installations involve:

• Fastening the support legs to the subfloor
• Leveling the tub correctly
• Silicone sealing the tub to surrounding walls
• Testing the drain and overflow systems

When installed correctly, this creates a rock-solid and leak-resistant installation.

GFCI Placement Recommendations

Hydrotherapy and heated walk-in tubs may require GFCI protection depending on the electrical
setup and local code requirements.

WalkInTubUSA recommends placing the GFCI device near an access panel whenever possible.

This makes resetting the system much more convenient if future access is needed.

Easy service access is an important part of long-term usability and maintenance planning.

Commercial and Condominium Requirements

Some condominium buildings or commercial installations may require additional plumbing or
safety devices.

One common example is a backflow prevention device installed within the water supply lines.

These devices are widely available and can typically be integrated directly into the supply
piping during installation.

Local building requirements should always be reviewed before installation begins.

Grounding and Bonding Recommendations

Proper grounding and bonding are important parts of a safe walk-in tub installation.

WalkInTubUSA recommends bonding the bathtub to the cold water line or another appropriate
grounding source according to local electrical requirements and installer guidance.

Electrical work should always be completed by qualified professionals familiar with local code requirements.

Install Shutoff Valves for Easier Service

Shutoff valves are strongly recommended for walk-in tub installations.

Installing shutoff valves near the bathtub allows future servicing or maintenance to be
completed without shutting off water to the entire house.

This is a simple installation detail that can make future maintenance much easier and more convenient.
