Cost for fitting a sink and shower

Hi, we are in the process of buying our new home and I am planning on converting a room (a converted garage with attached toilet (without shower, just toilet and sink) into a studio flat. I was wondering how much (and if it is even possible) it would cost to install a sink in the room and a shower in the toilet? As I note, there is already a toilet fitted but it does not have a shower. Presumably there would have to be drainage in place already which could help in these fittings?

On a side note, is it necessary to have building regulation for this?

Thanks a million!

"It is not necessary to have building regulations. As for the shower it depends which type of shower is needed and which price range you have in mind. Also which type of cubicle you need depending on price range. A bog standard shower and cubical you can buy for around £200. To fit it would cost minimum £250. These are only aproximate prices."

"Congratulations on your new home and your plans to convert the space into a studio flat! Adding a sink to the room and a shower to the existing toilet area is indeed possible, and the cost can vary based on a few factors.

Since there's already a toilet in place, the existing plumbing for drainage could potentially be utilized for the sink and shower installation. However, it's advisable to have a professional plumber assess the existing setup to ensure it meets the requirements for adding these fixtures.

The cost will depend on several factors such as:

Plumbing Requirements: Connecting the sink and shower to the existing plumbing lines.
Fixture Selection: The cost of the sink, shower, and their installation can vary based on the quality and type of fixtures you choose.
Labor Costs: Hiring professionals for plumbing and installation work.
Regarding building regulations, it's highly recommended to check with your local authorities or a building regulation officer to determine if any permits or regulations apply to this kind of conversion. Building regulations ensure safety standards are met for habitable spaces, especially when it comes to plumbing, electrical work, and structural changes.

Overall, the feasibility and cost can be better estimated by having a professional plumber and potentially a contractor assess the space and provide you with detailed quotes. This will give you a clearer idea of the expenses involved and whether any specific regulations need to be followed.

Good luck with your studio flat conversion—I hope it turns out exactly as you envision!"

"It is possible to do it, and from my knowledge you don't need any regulations! As for the price, it depends on the materials you need and want, and on how the pipping is in there! So if you want a fair price, you can get it only by assessment!"
