12 Steps to a Flawless Solid Surface Bathtub Installation​​

 

Installing a solid surface bathtub? Do it right the first time with these key steps—no leaks, no regrets.

 

​​1. Check the Floor Level First​​

A wonky floor means a wobbly tub. Use a level to confirm the surface is even before starting.

 

​​2. Inspect for Damage Before Installing​​

Look for cracks, chips, or scratches. If the tub’s damaged out of the box, don’t install it—get a replacement.

 

​​3. Align the Drain Perfectly​​

The tub’s drain must match the floor drain. Misalignment now means leaks and headaches later.

 

​​4. Team Lift – Don’t Go Solo​​

These tubs are heavy. Two people make moving and positioning safer and easier.

 

​​5. Protect the Surface During Install​​

Lay down cardboard or carpet to prevent scratches while maneuvering the tub into place.

 

​​6. Connect the Drainpipe Properly​​

Most tubs come with a flexible drain hose—use it. No need to buy extra parts unless specified.

 

​​7. Reinforce the base for stability during installation

Use temporary support materials, such as wooden or metal brackets to support the bottom, evenly distributed around the bottom and around the tub to ensure that the weight is not concentrated in one place to prevent shifting or tipping over time.

Temporary support materials need to be removed after the tub is installed.

 

​​8. Seal Wall-Mounted Tubs Tight​​

Run a bead of neutral silicone along the edges to block water from seeping behind the tub.

 

​​9. Leave Access Space for Freestanding Tubs​​

Keep a small gap between the tub and wall for future plumbing access.

 

​​10. Level Drop-In Tubs Before Sealing​​

Ensure the platform is perfectly flat, then leave a 1-2 cm gap for sealant to fill.

 

​​11. Clean Up Excess Adhesive Immediately​​

Wipe off any leftover silicone or glue before it dries—sloppy residue looks unprofessional.

 

​​12. Test for Leaks – Don’t Skip This!​​

Fill the tub and let it sit for 24 hours. Check underneath for any drips before calling it done.

 

​​Final Tip:​​ Take your time. Rushing leads to mistakes—and nobody wants a leaky bathtub. Follow these steps, and your install will be rock-solid.
