Bathtub refinishing: options, costs and preparation
A dull, discoloured or damaged surface does not necessarily mean replacing the entire bathtub. The material, condition and desired result determine the appropriate approach. A useful quote comparison distinguishes local repairs, surface restoration and complete refinishing.
Refinish, repair or replace?
Complete refinishing adds a new surface layer to the existing tub. Its dimensions, position and connections generally remain. If you want a different shape, more room or a new layout, also consider replacement or a bathroom renovation.
A single chip may only need a local repair. Some acrylic or mineral-based surfaces can also be restored, depending on their condition. These jobs differ from a complete new coating. Ask why the proposed approach addresses the problem and which areas will be treated.
The term re-enamelling is sometimes used for on-site work. However, the applied layer is not necessarily identical to factory-made enamel. The actual process, its requirements and its care instructions matter more than the label.
The existing material determines the options
Enamelled steel, enamelled cast iron, acrylic and mineral-based materials require different treatments. Name the material if you know it. Otherwise, the specialist can identify it from the bathtub or during a visit.
A new coating needs a suitable substrate. Cracks, movement, significant rust or leaks should be assessed before work begins. Covering a damaged area does not automatically resolve its cause. Describe what you can see without having to make a technical diagnosis yourself.
| Observation | What to assess |
|---|---|
| Dull or discoloured surface | Restoration or complete refinishing? |
| Isolated chip | Local repair and suitable colour matching. |
| Crack, movement or leaking water | First assess the cause and suitability for repair. |
| Previously refinished tub | Condition and possible removal of the old coating. |
Mention previous coatings and existing damage
Previous refinishing can change the work required. Peeling or poorly bonded layers need different preparation from a suitable original surface. Say whether the tub has been coated before. If you do not know, the quote should include an assessment and explain how potential additional work will be agreed.
Approximate length and width help with an initial enquiry. For a local repair, the number, position and extent of damaged areas matter more. A rectangular tub measuring around 170 × 75 cm and several large corner baths are different jobs. You can mention unusual shapes, inaccessible edges or special fittings in the shared notes field.
Check whether cleaning, damage repairs and preparation around the edges are included. The contractor should explain how the bathroom, taps and adjacent surfaces will be protected.
How much does bathtub refinishing cost?
One published regional tariff lists CHF 980 net for a standard-size white tub and CHF 170 extra to remove an old coating. Travel within Zurich is subject to tariff conditions; parking is excluded. This is a limited price example, not a Swiss average.
These two items total CHF 1150 net, or CHF 1243.15 with 8.1% VAT. Different dimensions, condition, colour or travel can change the price. Request the complete final amount for your actual job.
A retail material kit is not a comparable price for professionally completed work. Replacing a tub also involves different items from refinishing it. Compare the scope before comparing the amounts.
| Cost item | Check in the quote |
|---|---|
| Preparation | Cleaning, substrate assessment and removal of old layers. |
| Damage | Which areas will be repaired and to what extent? |
| New surface | Areas covered, colour and agreed finish. |
| Connections and joints | Clarify silicone, waste fittings and required plumbing. |
| Additional requirements | Slip-resistant treatment and special fittings. |
| Total | Travel, parking, VAT and potential surcharges. |
Agree the colour and any slip-resistant finish
For complete refinishing, you may want a new colour or something close to the existing appearance. Local repairs mainly need a suitable transition to the retained surface. White alone does not define a precise shade.
Agree the desired colour and expected result before work starts. Differences are particularly noticeable beside the basin, toilet and wall tiles. A sample or colour reference helps base the decision on a visible result.
Additional slip resistance must suit the proposed coating and be expressly agreed. It is neither automatically included nor a guarantee against slipping. Ask how that finish should be cleaned.
Separate working time from the return to use
The contractor defines preparation, application and release for use according to the system. Agree access, clear working space and the necessary bathroom conditions. Protection and ventilation belong in the plan; refinishing should not be improvised between other ongoing jobs.
The end of the contractor’s visit does not mean immediate use for every process. Confirm exactly when water, cleaning products and normal use are permitted. Same-day claims only apply when the proposed system and actual working conditions allow them.
Allow for renewed silicone joints and any additional work. A clear return-to-use time is especially helpful in a household with only one bathtub.
Care instructions must suit the new surface
After refinishing, follow the guidance for the new coating. Advice for the original enamel or acrylic cannot be transferred without checking. Agree suitable cleaners and accessories; a blanket recommendation for aggressive descalers or abrasive products would be inappropriate.
Slip-resistant areas also require suitable cleaning. Check compatibility before using mats, suction accessories or particular bath additives. Keep the care instructions alongside details of the treatment applied.
Impacts, subsequent damage and normal wear differ from poor adhesion. If a warranty is offered, ask for its scope, conditions and contact in writing. This does not establish a universal service life.
Compare complete quotes
Give each contractor the same starting information. For several tubs, make the number and differences in size or damage clear. Resolve outstanding assessments before commissioning so that an attractive base price does not hide a different scope.
- Define the task. Distinguish full refinishing, a colour change and local repairs.
- Describe the existing tub. Give known material, measurements, visible damage and previous treatments.
- Compare the scope. Check preparation, joints, travel and the total together.
- Agree the handover. Confirm the result, return to use and care guidance.
Frequently asked questions
Can every bathtub be refinished?
Not automatically. The material, substrate and condition must suit the process. Cracks, movement or leaks require assessment of the cause first.
Does the bathtub have to be removed?
On-site work can be performed on an installed tub. The contractor checks whether access and condition are suitable and what ancillary work is needed.
Can a small chip be repaired locally?
That can be appropriate if the surrounding surface and substrate are suitable. Describe the location and size; a complete new coating is not necessary for every isolated defect.
How long will the bathtub be out of use?
This depends on the proposed process and any ancillary work. Ask for the actual release time rather than relying on a general waiting period.
Do I need exact measurements and material details?
Known information and approximate measurements are enough for an initial enquiry. Unknowns can be assessed later. For local damage, a short description is more useful than the exact dimensions of the entire tub.
