Basic Bathroom Renovation

Average Cost: $5,000-$15,000 (or $2,000 to $5,500 for DIY)

You won't require a big budget for a small bathroom because there are fewer plumbing fixtures and lesser square footage. To stay within a low budget, keep the original bathroom layout as is. Changing the layout of your bathroom will usually be the biggest cost as it will involve more complex plumbing work - If you can keep your layout as is, you'll make big savings. This is ideal for those on a tight budget and assuming you don’t need any structural work or major renovations like re-tiling; plumbing pipes, or making any structural changes to the layout of your bathroom.

This can include updating old furnishings and fixtures, or anything that does not involve electrical work or movement of plumbing. However, it may vary from job to job.

Here’s what to expect to change in this renovation project:

  • Re-coating or resurfacing existing tiles
  • New taps and vanity
  • New mirror
  • Re-coating an existing bathtub
  • Installing a new toilet and a basin
  • Showerhead and tap
  • Install or change towel racks
  • Install exhaust fans

Shower Base

When it comes to a shower base, there are three main options: polymarble, tiled, and a shower over bath.

A polymarble shower base is a hard-wearing, solid, fully-moulded material ideal for bathroom surfaces. The tiled shower base gives you the stylish look of a tiled floor while being structurally sound and completely waterproof.

A shower over a bath is not a common choice unless you need a bath but are pressed for space.

Shower Screen

Thinking about the type of shower you have is a good place to start when you’re trying to choose between options for shower screens. Whether you go for a fully frameless, single glass screen, semi-frameless or even no screen, it can add a modern, classic or luxurious look.

Bathtub

Floor and Wall Tiles

Floor and wall tiles are durable and beautiful design elements that are essential to bathrooms. They can give a room a rustic, and elegant ambience, and can help tie together an overall colour scheme. When considering tiles, you need to choose a colour, finish, and size that fits with your design.

Toilet

Features to consider when choosing your toilet include height, bowl shape, colour, style, and flushing technology.

Towel Rails

Towel rails are not what usually springs to mind when one thinks about renovating or building a bathroom. However, not only do towel rails perform a necessary role in providing storage space for towels, but they can also help add a design flair to an ordinary bathroom.

There are four basic types of towel rails: freestanding towel rails, wall-mounted towel rails, ladder/rack towel rails and heated towel rails. Each variety has its pros and cons, so it’s important to establish which will work best in your room.

Lighting and Electrical Setup

Lighting is as essential a component as the fittings. Other than general lighting, the most important function of lighting in a bathroom is to light your face when using the vanity mirror. You can also give your bathroom space a design-forward look by embracing some of these bathrooms lighting tips:

  • Daylight is a priority: when it comes to windows think big and, if possible, floor-to-ceiling.
  • Keep it private: Frosted and obscure glass provides good privacy
  • Turn up the heat: mould and mildew can cause big problems so good airflow is essential
  • Small spaces: ff there’s no space for big windows a skylight may be the answer
  • Task lighting: for putting on make-up or shaving, a strong, even light is needed around the mirror and vanity
