If your shower is not working correctly, I am happy to make an obligation-free inspection visit to identify what's wrong and the best solution, assuming that you are happy in principle with my hourly rate.

Mixer Showers
If your mixer shower has stopped working correctly I can probably fix it by ordering and fitting a new thermostatic cartridge. Especially with shower valves that are built-in behind the tiling, this is the cheapest solution. By temporarily removing the existing cartridge to take photos and measurements that I send to my suppliers, I can usually get an identification of the correct part. In some cases, it might be necessary to replace the shower, which might include some retiling. If the shower has an exposed valve, or bar valve, replacement of the whole valve is usually straightforward and may be a better option than just replacing the cartridge.

Electric Showers
When electric showers fail outside their warranty period, except with higher end models, the price of a new shower is such that it is usually more economical in the long term to replace the shower with a new one than to try to repair it. You then have the assurance of a new 2 year warranty. I am not an expert at replacing the internals of an electric shower, and if I replace one faulty component you never know when another component might fail.

Cost
At the end of a job, my bill is always calculated according to my hourly rate - £75 for up to an hour + parts (Mon-Fri 9am - 5pm within 10 miles of Salisbury), then £60/hr to the nearest 0.1 hour. For jobs exceeding two hours it's simply £60 per hour, start to finish, plus parts. I am not VAT registered, so there is no additional VAT to pay on my labour. My rates are based on the Average UK Plumber day rate as published by Checkatrade.

In cases where I need to make my inspection visit, I will talk you through the likely cost of each option, whether repair or replacement, including parts and likely labour cost. Replacement of an electric shower is typically a 2 hour job. Replacement of a mixer shower is more variable, depending on the type of shower and whether the valve is external or built-in behind the tiling. When possible, replacement of a thermostatic cartridge usually takes about 1 to 1.5 hours.

Shower Pumps
If a shower pump develops a fault, it is usually time to replace it with a new one. I will talk you through the various options, including positive and negative head, and what pressure rating of pump you need. Expect replacement of a shower pump to take about 2 to 2.5 hours. The main cost is the price of the pump, but I will help you source one at the best price.

Over-bath shower screens
Replacement typically takes about 1.5 to 2 hours.

Leaking Showers
If a leak is evident on the ceiling below, I first check that it is not from the shower's waste pipework (it rarely is but this needs to be eliminated as a possible cause first). The most common cause is that the silicon around the tray or bath has perished and needs replacing. This is typically a 1 to 1.5 hour job, most of which is the time taken to remove the old silicon and clean up the tiles. Another possible cause is that cracks have appeared in the grouting between the tiles and water has started to seep behind them. This loosens the tile adhesive, and also usually damages the plasterboard behind them. If this is the case, the lower two or three rows of your shower will need retiling and some of the plasterboard will probably need replacing. I am happy to do tiling and plasterboard repairs, but expect it to take something like 10 hours in total, spread over several visits.

Trays, enclosures, and bathroom installation
Where trays, enclosures or baths need replacing, please contact some bathroom installers for quotes. I prefer to focus on the smaller jobs, and always charge by the hour.
