Bathtub Installation Mistakes to Avoid: Tips for a Smooth Setup

Placing a bathtub looks simple, but small mistakes can cause big problems. These problems include leaks, inadequate drainage, cracks, strange noises, and a tub that isn't level. This guide will show people's most common errors when installing a bathtub. It will explain why they are bad and give you clear tips to get the job done right. You will also see why a well-made tub, like those from HERA Bathroom, can make the process much easier.

Why Correct Bathtub Installation Matters

A bathtub is one of the heaviest things in your bathroom. It has to hold a person plus over 200 litres of water. If the base, seals, or pipes are not installed correctly, you could end up with:

• Water leaking into your walls or floor
• Cracks or a sagging tub from uneven support
• Water that doesn't drain properly
• Creaking and noisy floors
• Costly repairs later on

Doing the Bathtub installation from the start will save you money, time, and a lot of stress.

Common Bathtub Installation Mistakes (and how to avoid them)

Here are the errors we see most often, along with simple ways to fix them.

1. Poor measurement or ignoring plumbing rough-ins

• The Mistake: Choosing a tub that doesn't match your drain pipe or wall frame. Sometimes people forget to measure carefully.
• Why it's bad: The tub won't fit against the walls properly. It can stress the pipes, and you might have to redo all the plumbing.
• The Tip: Before you buy a tub, check your "rough-in" measurements. The measurement is the distance from the wall to the centre of your drain pipe. Use these exact measurements when you order your new tub.

2. Not leveling or supporting the bathtub correctly

• The Mistake: Not making sure the tub is perfectly level or leaving empty space underneath it.
• Why it’s bad: The tub can sag or flex when you stand in it. Over time, this can cause the material to crack.
• The Tip: For many tubs, you should spread a special mortar or setting compound on the floor before placing the tub. This creates a solid, level base. Always use a long level tool to check that the tub is even from all sides. Make sure all the adjustable feet are tightened.

3. Skipping waterproofing or sealing steps

• The Mistake: Thinking that a little caulk is enough to stop water, or not using proper waterproof materials behind the walls.
• Why it’s bad: Water will sneak behind the walls or under the tub. This causes mold, rot, and can damage the structure of your home.
• The Tip: Use a waterproof sheet or board on the walls behind your tiles. Make sure it overlaps the top edge of the tub. Always use a high-quality silicone caulk made for bathrooms to seal the joint between the tub and the wall.

4. Poor drain and waste installation

• The Mistake: Damaging the rubber seals, putting the drain pipe together wrong, or screwing the parts too tight.
•  Why it’s bad: This can cause leaks at the drain. If you overtighten the drain, you can even crack the tub.
•  The Tip: Use a little dish soap to help the rubber seals slide into place easily. Make sure the drain pipe is straight before you tighten everything. Always pour water into the tub to test for leaks before you close up the walls.

5. Rushing framing or neglecting wall backing

• The Mistake: Not building a strong wooden frame around the tub to support it and the walls.
• Why it’s bad: The tub can move, your wall tiles can crack, and you won't have anything solid to attach things like faucets or grab bars to later.
• The Tip: Build a strong frame of wooden studs around the tub. Add extra wooden blocks inside the walls where you know you will need to install grab bars or shower handles.

6. Ignoring manufacturer instructions

• The Mistake: Not reading the instructions that come with the tub or using the wrong screws and parts.
• Why it’s bad: You could break your new tub, install it unsafely, or void the warranty.
• The Tip: Always read the instruction manual from start to finish. Use only the screws and parts that came in the box with the tub.

7. Skipping intermediate tests or inspections

•  The Mistake: Putting up walls and tiles before you are sure there are no leaks.
• Why it’s bad: If you find a leak later, you will have to smash your new tiles and break open the walls to fix it.
• The Tip: After the tub and pipes are in, fill the tub with water and check everywhere for leaks. Also, stand in the tub to see if the bottom feels soft or moves. Fix any problems now, before you finish the walls.

8. Poor finishing (caulk and trim)

The Mistake: Doing a messy job with the caulk or leaving gaps.

•  Why it’s bad: Even a tiny gap will let water in, causing damage. A messy caulk job also looks bad.
• The Tip: Use painter's tape to get straight, clean lines when you apply caulk. Smooth the caulk with a wet finger or a special tool. Wipe away any extra caulk right away.

Example: A Real-Life Tub Alignment Problem

During one bathroom remodel, the installers found a problem. The drain hole in the tub was 15 mm away from the drainpipe in the floor. If they had forced the tub to fit, the pipes would have been under stress and would have leaked later.

Instead, they took a little extra time. They made a small adjustment to the wooden floor frame and the mortar base. This allowed them to position the tub so the drain lined up perfectly. It took a bit more work that day, but it prevented a major leak that would have ruined the new tiles.

If the tub had been designed with helpful features and a little flexibility like HERA bathroom, this extra work might not have been needed at all.

Final Thoughts

Installing a bathtub is trickier than it looks. Small mistakes with leveling, the drain, or seals can lead to very expensive repairs.

You can avoid these common errors. Always double-check your measurements first. Make sure the tub has full support underneath. Seal all the edges properly. Always test for leaks before the walls are closed up.

Using a simple checklist is a great idea. It helps you remember every important step.

A well-designed tub makes everything easier. HERA Bathroom tubs are made for simpler installation. Their design helps you prevent errors. This means you spend less time fixing problems. You can focus more on the final finishing touches.
