Cracks, chips, small holes and worn finishes in fibreglass baths can usually be repaired on site, at a fraction of the cost of a new bath and without tearing out tiles, panels and plumbing.
Fibreglass baths are lightweight, warm to the touch and affordable, which is why so many UK homes have one. But they are also more vulnerable than heavier baths. A dropped bottle can chip the surface. A bath that flexes underfoot can develop cracks. Years of cleaning can leave the finish dull, scratched or stained.
When damage appears, many people assume the bath has to go. Replacing it, though, is rarely just a bath swap. Tiles around the edge are often disturbed, the bath panel may need replacing, taps and wastes are disconnected, and the bathroom is out of use for days.
At Albion Restore Ltd, we are London-based, CHAS-accredited surface repair specialists with over 10 years of experience repairing plastic, ceramic and other surfaces. Our mobile team carries out fibreglass bath repair in your home across London and the surrounding areas.
This guide explains the damage we repair, why fibreglass baths crack, how the repair process works, and when replacement genuinely makes more sense.
What is a fibreglass bath?
A fibreglass bath, sometimes called a GRP bath (glass reinforced plastic), is made from layers of glass fibres bonded with resin. The inside surface is finished with a smooth, coloured coating called gelcoat, which gives the bath its glossy look.
Fibreglass is often confused with acrylic, and the two are repaired in similar ways. The main difference is how they are built:
| Feature | Fibreglass (GRP) bath | Acrylic bath |
|---|---|---|
| Construction | Fibreglass layers with a gelcoat surface | Acrylic sheet, usually reinforced underneath |
| Weight | Very light | Light |
| Surface | Gelcoat, can wear thin over time | Solid colour through the acrylic layer |
| Common damage | Cracks, chips, worn gelcoat, flexing | Scratches, chips, stress cracks |
| Repairable? | Usually yes | Usually yes |
If you are not sure which type you have, do not worry. We identify the material during our assessment and choose the right repair method.
Types of fibreglass bath damage we repair
Cracks. Cracks in fibreglass baths usually appear in the base, near the waste or around the feet. They range from fine hairline cracks to longer splits.
Star cracks and stress cracks. Small, spider-like cracks often appear where something heavy was dropped, or where the bath flexes repeatedly in one spot.
Chips. Dropped bottles, shower heads and razors can chip the gelcoat, especially on the rim and base.
Small holes. Heavy impacts can punch small holes through the bath, which must be repaired quickly to stop water escaping.
Worn or dull gelcoat. Years of abrasive cleaning can wear the gelcoat thin, leaving the bath dull, rough or patchy.
Stains and discolouration. Hair dye, limescale and some cleaning products can stain the surface, and older baths can discolour or yellow.
Scratches and burn marks. Grit, jewellery and cigarettes can leave marks in the surface that do not clean off.
Why fibreglass baths crack
A repair lasts longest when the cause of the damage is understood and dealt with.
Lack of support underneath. This is the main cause of cracks. Fibreglass baths need a solid cradle or support under the base. If the bath was installed without enough support, or the supports have settled, the base flexes every time someone stands or sits in it. Over time, that movement causes cracks.
Loose or uneven feet. Bath feet that are not adjusted properly, or have worked loose, put stress on certain points.
Impact. Heavy objects dropped into the bath can crack or hole the surface.
Standing in the bath to shower. Baths used as showers take concentrated weight on a small area, which increases flexing.
Age. Older fibreglass baths can become more brittle over time.
If your bath flexes or creaks when you stand in it, that movement needs to be addressed for a crack repair to last. We will always explain this honestly.
Our fibreglass bath repair process
- Honest assessment. We identify the bath material, check for movement and leaks, and tell you plainly whether repair is the right choice.
- Checking support. If the bath flexes, we explain what is needed to support it properly. A crack repair on a moving bath will not last.
- Protection and preparation. Taps, tiles and the bath panel are protected. The damaged area is cleaned, dried and prepared so repair materials bond properly.
- Repairing the damage. Cracks, chips and small holes are filled and, where needed, reinforced so the repaired area is strong as well as smooth.
- Levelling. The repair is levelled flush with the bath surface, so there is no ridge or dip.
- Colour matching and finishing. We match the colour of your bath, whether white, ivory or a coloured suite, and polish the area to the same gloss as the surrounding surface.
- Curing and aftercare. We explain how long to wait before using the bath and how to clean it to protect the repair.
Many fibreglass bath repairs are completed in one visit, with curing time before the bath can be used again. Larger repairs or full resurfacing take longer, and we confirm timings first.
Restoring a dull or stained fibreglass bath
Not every bath problem is a crack. Many people contact us because their bath simply looks old. The gelcoat has lost its shine, the surface feels rough, or stains will not shift no matter how much it is cleaned.
Because fibreglass baths have a thin gelcoat surface, heavy scrubbing and abrasive cleaners gradually wear it down. Once the gloss is gone, the surface stains more easily, which makes it harder to keep clean.
Restoring the surface brings back an even colour and a smooth, glossy finish, so the bath looks fresh again without the cost of replacement. It is a popular choice before selling a home, between tenancies, or when the rest of the bathroom is still in good condition.
DIY fibreglass bath repair kits
Fibreglass bath repair kits are easy to buy, and for a very small chip they can be a short-term fix. For cracks, holes and larger damage, they have serious limits:
- No fix for the cause. If the bath flexes, a DIY repair will usually crack again.
- Weak repairs on holes and cracks. Without proper reinforcement, filler alone may not hold under weight and hot water.
- Colour mismatch. Kit colours rarely match the exact shade of an older or coloured bath.
- Uneven finish. Without careful levelling and polishing, the repair is easy to see and feel.
- Harder professional repair later. Failed DIY material must be removed before a proper repair.
If your bath has a hole or a crack that could leak, a professional assessment is the safer option.
Fibreglass bath repair vs replacement
| Factor | Fibreglass bath repair | Bath replacement |
|---|---|---|
| Cost | A fraction of replacement | New bath, plumber, tiler, possibly new panel |
| Time | Often one visit plus curing | Several days of work |
| Disruption | Bath, tiles and panel stay in place | Tiles, sealant, taps and waste disturbed |
| Matching | Original bath kept | Coloured or unusual sizes can be hard to match |
| Waste | Bath stays out of landfill | Old bath scrapped |
Repair is usually right for:
- Hairline cracks, star cracks and chips
- Small holes from impact
- Dull, worn, scratched or stained surfaces
- Coloured suites you want to keep
Replacement may be better when:
- The bath is split across a large area or badly deformed
- The bath cannot be properly supported
- You are completely redesigning the bathroom anyway
We repair existing baths only and do not sell new ones, so our advice is always honest.

Fibreglass bath repair: frequently asked questions
Can a cracked fibreglass bath be repaired?
Yes, in most cases. Hairline cracks, star cracks and many longer cracks can be repaired. If the bath flexes, the support underneath must be improved for the repair to last.
Can you repair a hole in a fibreglass bath?
Small holes from impact can usually be repaired and reinforced. Stop using the bath until it is fixed, to prevent water escaping.
How do I know if my bath is fibreglass or acrylic?
Fibreglass baths often have a slightly thinner feel and a gelcoat surface, while acrylic has solid colour through the surface layer. We will identify it during our assessment.
Will the repair be visible?
The aim is a repair that is very hard to spot in normal use. Results depend on the colour, finish and size of the damage, and we explain what to expect first.
How long before I can use the bath?
Repair materials need time to cure. We will tell you exactly when the bath can be used again.
Can a dull fibreglass bath be restored?
Yes. Worn, dull and stained surfaces can be restored to an even, glossy finish without replacing the bath.
