Our comprehensive guide is chock-full of valuable suggestions and information that will help you whether you’re planning to construct a new bathroom or remodel it.

Do I Need A Professional Builder To Install My Bathroom?

Some builders can do all of the work necessary for bathroom installation. If you employ a builder to oversee and manage the bathroom installation, they may also recruit and coordinate the craftsmen on your behalf. Your path should consider numerous deliberations, including your budget, DIY skill level, and the amount of effort needed.

There are various common situations in which hiring a builder to supervise your bathroom makeover makes sense, including:

  • Building a fresh bathroom from the bottom up.
  • When party walls are at risk.
  • When interior barriers must be constructed or removed.
  • Where new fixtures necessitate the reinforcement of old floors.
  • Structural calculations, waterproofing, and drainage concerns are frequently encountered when constructing a wet room.
  • Where permission or conformity with building rules (also known as building regs) is necessary.
  • When selecting fixtures and fittings that need expert installation, such as hefty, big format stone tile or wall-hung sanitaryware.
  • If you cannot undertake the bathroom fitting job alone (perhaps due to time constraints).
  • Using a builder to supervise the bathroom installation means you have an expert on your side who can call on their trusted trades.

How To Plan A Bathroom?

If you’re having a builder install the bathroom, communicate with them right away about what you want from the new area. Most Master Builders can assist you with bathroom design, so include them in your project. When it comes to outlining the practicalities of layouts, fittings and the anticipated expenses involved, an experienced builder may be useful.

  • Begin with the toilet’s placement, looking at the location of the old dirt pipe and where it enters the room — this will show you the optimum site for the new toilet, which you can then work around.
  • Mark out any existing characteristics that may affect the bathroom plan.
  • You may then experiment with where to arrange sanitaryware keeping in mind to draw everything to the same scale.
  • If you hire a builder to manage the job, they may collaborate with you on the bathroom plan or possibly come up with many layout options for you.
  • It is critical to assume who will use the restroom. Anyone with children, for example, might wish to take a bath and should consider easy-to-clean and non-slip surfaces. On the other hand, a walk-in shower and twin basins would be more suited to a major en suite bathroom.

Are You Remodeling A Bathroom Or Beginning From Scratch?

A basic upgrade is the best solution for those on a tight budget. Keep the present arrangement in place to prevent relocating pipes. However, include more contemporary sanitaryware, additional storage, or a hot towel warmer. Moving items around or enlarging the area is common when remodeling a bathroom. At the design stage, you should always address the relocation of plumbing, waste, pipes, and electrics with your builder.

If the bathroom will be built in a totally new area in the case of a construction or bigger refurbishment project. A builder or other specialist will be required to check that your new plumbing complies with building standards.

What Building Regulations Do I Need To Consider?

If replacing bathroom fixtures and fittings, you may realize that more wiring or pipes are required. If you are remodeling a bathroom rather than building a new one, you will most likely have services such as electricity, plumbing and garbage connected. Any electrical work near or around wet areas, such as bathtubs and showers, must comply with building standards.

When the job is finished, your employees should send over any relevant certification proving that the work conforms to Building Regulations.

Average Bathroom Renovation Costs

Size, fixtures, and location are all factors that influence the price of your dream bathroom. Natural stone tiles, underfloor heating, a new lighting scheme, designer hot towel warmers, and decorative accessories must all be budgeted for.

Standard acrylic baths and basic electric showers will be at the lower end of the price spectrum. High-end products like natural stone bathtubs and glass basins need a bigger expenditure. The typical cost of materials for a basic new bathroom is currently £4,500.

High-quality bathroom suites are significantly more expensive than the usual job. Attempting to fit them yourself will waste time if something goes wrong.
