I’ve refinished hundreds of tubs professionally and I’ve seen plenty of DIY jobs — good ones and bad ones. Here’s what actually matters when deciding whether to do it yourself.
The Pros
Cost Savings Are Real
This is the big one. A professional refinishing job runs $350–600 in most markets — see how much bathtub refinishing costs for a full breakdown. A quality DIY kit is $30–80. Even if you buy extra supplies — a better respirator, drop cloths, quality tape — you’re still under $150 in the worst case. The savings are significant enough to take seriously.

You Control the Prep
The most common cause of premature peeling on a professional refinish is rushed prep work. Time is money for a contractor — some cut corners on cleaning, etching, or drying time. When you do it yourself, you know exactly what was done at every step. You can take as long as you need.
No Scheduling, No Strangers in Your Home
You work on your timeline. No waiting for an appointment, no coordinating access, no strangers working in your bathroom.
Good Kits Are Genuinely Available
Modern DIY kits use real epoxy chemistry — not watered-down coatings. Rust-Oleum’s two-part Tub & Tile kit is the same basic epoxy approach pros use, just in DIY-sized quantities. The chemistry works.
Skill That Transfers
Once you’ve done it right once, you understand the process for life. Other tubs, tile surrounds, sinks — the same principles apply.
The Cons
The Fumes Are Serious
This isn’t a con that should stop you — but it’s one that deserves respect. Epoxy coatings in an enclosed bathroom produce fumes that can cause headaches, dizziness, and respiratory irritation. You need:
- A proper organic vapor respirator (not a dust mask)
- Ventilation — window open, fan exhausting air out
- Ideally, pets and other household members out of the area
If your bathroom has genuinely poor ventilation and can’t be adequately aired out, this becomes a more serious concern.
The Prep Is Time-Consuming and Unforgiving
The actual coating application takes an hour. The prep takes 2–3 hours. Sanding, cleaning, etching, drying, taping — all of it matters. Skip or rush any step and the finish will fail early.
Some people underestimate this and treat it like painting a wall. It’s not like painting a wall.
Cure Time Is a Real Inconvenience
You cannot use the tub for 48–72 hours after application (some products say longer). If you only have one bathroom with a tub, that’s a real inconvenience. Plan accordingly.
Full coating hardness takes 5–7 days. During that window, avoid harsh cleaners and abrasive scrubbers.
DIY Finish vs. Professional Finish — There Is a Difference
A professional with spray equipment and commercial coatings produces a smoother, more uniform finish than a DIYer with a roller. The spray method lays down an extremely even coat — a roller leaves a slight texture. In practice, this difference is hard to notice in daily use, but it’s real.
If You Mess Up, It’s Harder to Fix
A peeling DIY finish is annoying to fix. The existing coating has to be stripped or sanded off before re-doing — which is more work than starting fresh. Pros can spot-repair their own work easier because they know exactly what they applied.
This is why following the instructions exactly the first time pays off. The complete DIY bathtub refinishing guide is worth reading all the way through before you open any product.
Kits Have Limitations
DIY kits are designed for relatively smooth, non-damaged surfaces. If your tub has:
- Deep gouges or chips
- Significant rust
- Cracks in the porcelain or fiberglass
- Prior coatings that are failing
…you have additional repair steps before you can coat. A bathtub repair kit handles chips and cracks before you refinish. Kits aren’t magic — they don’t fill damage, they just coat surfaces.
The Bottom Line
DIY makes the most sense if:
- Your tub is stained, yellowed, or scratched but structurally intact
- You have decent ventilation in the bathroom
- You can be without the tub for 3 days
- You’re willing to do the prep properly
It makes less sense if:
- Your tub has structural damage that needs repair first
- You genuinely can’t ventilate the bathroom adequately
- You need the tub back in service in 24 hours
- The tub is past its useful life entirely (replacement is the right call)
For most people with a tired-looking tub, DIY refinishing is a completely reasonable project that saves hundreds of dollars. Just don’t skip the prep.
