A tub-to-shower conversion might seem like a straightforward project, remove the existing bathtub, add a new shower, and you’re done.
But like any conversion project, there are plenty of mistakes people make with doing a tub-to-shower conversion that can lead to frustration, costly repairs, or wasted effort.
Let’s break down these pitfalls and talk about how to get it right.
Quick Summary
- Skipping the planning stage, like failing to measure accurately or overlooking waterproofing, leads to costly errors. Planning ensures the right materials, sizes, and features for a successful tub-to-shower conversion.
- Using cheap materials or attempting DIY without experience can result in leaks, mold, or poor installation. Investing in durable materials and professional contractors ensures long-lasting and efficient results.
- Overlooking storage, accessibility, or cohesive design can affect functionality and appearance. Features like niches, grab bars, and matching tiles enhance the shower’s usability and blend with the bathroom’s style.
Mistakes Made With Tub to Shower Conversions
1. Skipping the Planning Stage
Planning might not sound exciting, but it’s the backbone of any successful bathtub to shower conversion. Without a solid plan, you risk making big mistakes like buying the inappropriate size shower or installing a shower pan that doesn’t fit the tub area.
Take the time to measure everything in your bathroom—from the dimensions of the existing bathtub to the surrounding wall.
Don’t forget to factor in space for shower doors that can either swing or slide open without hitting nearby fixtures.
If you’re unsure about plumbing or materials, work with a professional team to avoid common mistakes like mismatched components or poor drainage.
2. Removing the Only Tub
One of the most common mistakes is removing the only bathtub in the house. While a shower conversion is a great upgrade, many homeowners value having at least one bath for things like bathing kids or soaking laundry.
If you’re set on a tub-to-shower conversion, make sure there’s another bathroom with a tub, especially if you’re considering selling your home.
For many homeowners, it’s all about maintaining versatility and meeting the needs of potential buyers.
3. Choosing Cheap Material
Using cheap materials might seem like a way to save money, but it’s a big mistake that can lead to cracks, discoloration, or worse—mold. The cheapest materials often don’t hold up under daily use, meaning you’ll face replacements or repairs sooner than you’d like.
Instead, go for quality options like durable shower pans, non-porous tiles, and long-lasting fixtures. This ensures your shower installation lasts for the long run and looks great doing it.
4. Ignoring Waterproofing
Waterproofing isn’t optional. Forget it, and you’ll likely end up with leaks, mould, or water damage to your floor and walls.
Seal every part of your new shower, including the shower floor, edges, and corners. In older homes, waterproofing is even more important because of potential wear and tear in the plumbing system.
5. Attempting DIY Without Experience
Let’s be honest, those DIY shows on TV make everything look easy. But unless you have the skills and tools to handle plumbing, tiling, and installation shower, attempting a bathtub to shower conversion yourself can lead to big mistakes.
Most DIY projects end up costing more because of mistakes that need fixing.
Hiring professional contractors ensures the job is done right the first time, saving you time and stress.
6. Poor Drain Placement
Drains may not seem exciting, but they’re a crucial part of your tub to shower conversion projects.
A poorly placed drain can cause water to pool, damaging your shower flooring or creating a slipping hazard.
Stick with the existing tub drain placement unless absolutely necessary. Relocating it adds complexity to the plumbing system and increases costs.
7. Overlooking Storage
Not planning for storage during your tub-to-shower conversion is a common mistake. Without built-in niches or shelves, you’ll end up with bottles and soap cluttering the floor.
Add a niche or a corner shelf to keep things organised. Just make sure it’s positioned for easy access and away from constant water splashes.
8. Forgetting About Accessibility
Even if you don’t need grab bars or a low-threshold entry now, they’re worth considering for the future. Features like a fold-down seat or a wide entry make your new shower more functional and safer for all ages.
9. Blocking Natural Light
If your existing bathtub area has a window, think carefully before blocking it. Natural lights make a bathroom feel bigger and brighter, improving both the aesthetics and functionality of the space.
To keep the light while maintaining privacy, consider frosted or textured glass for the shower door or windows.
10. Choosing the Wrong Shower Doors
Picking the wrong shower door can cause all kinds of headaches. Short doors might not suit taller individuals, and bulky doors that swing open can bump into nearby fixtures if you don’t have enough space.
Sliding doors or frameless glass designs are great for maximising room and giving your bathroom a modern look.
11. Neglecting Hidden Damage
Pulling out an old tub often reveals issues like broken pipe, rotting wood, or damaged subfloors. Skipping repairs is a big mistake that could lead to structural problems later.
Take the opportunity to fix any hidden issues before completing your tub-to-shower conversion. It’s better to address these problems now than face costly fixes down the line.
12. Installing the Wrong Size Shower Pan
A poorly fitting shower pan is one of the most frustrating errors in a shower conversion. An ill-sized pan can lead to leaks, instability, and repairs.
Measure your bathtub area carefully and choose a shower pan that fits like a glove.
If you’re unsure, consult a professional team to get it right.
13. Mismatched Aesthetics
Your new shower should feel like part of your bathroom, not an afterthought. Mismatched tiles, colours, or fixtures can make the space look disjointed.
Stick to a cohesive design that ties in with the rest of the room. It’s a small detail that makes a big difference.
14. Not Allowing Enough Time
Underestimating how long conversion projects will take is a common mistake.
Rushing through a shower installation can lead to uneven tiles, misaligned fixtures, or poorly sealed edges.
Allocate plenty of time for the job and add a buffer for unexpected delays. Good work takes time, and it’s worth the wait.
15. Why You Need the Right Team
A professional contractor can make all the difference in your tub-to-shower conversion. From selecting the right materials to addressing unexpected issues like broken pipes, a professional team ensures the process runs smoothly.
