Factors determine the cost of a bathroom renovation

• Whether you need to undertake structural work or not
• The cost of floor tiles, wall tiles, fittings etc - are you going down a high end or budget route?
• Additions such as a skylights or new windows
• The size of the bathroom - is it an ensuite or a large family bathroom?
• Whether you’re moving plumbing and fixtures
• Whether you’re installing a new bathroom altogether
• Luxury elements like underfloor heating
• Revamping your bathroom lighting and how much electrical work you need

• 1. Make a list of your bathroom likes and dislikes ((Think about what you do and don't like about your current bathroom. Then put together a scrapbook of any new features, fixtures and fittings you'd really like to have when you renovate. Collect a few sample tiles and colour swatches so you can see how colours and textures will work together.)
• 2. Think about your current bathroom plumbing and electricity(Consider where your current bathroom plumbing and electricity are positioned in the room. The less you need to reposition these, the less you will need to spend on tradies. You should also consider how well your old inlets and outlets will work with new fixtures and fittings)
• 3. Measure up your bathroom walls, windows and doors(Measure up the whole room to work out how much space you have to install any new fixtures and fittings. Remember you can never have enough storage – especially in a bathroom – so think about ways you can fit some more in. Don't forget that all wet area rooms such as bathrooms must be waterproofed.)
• 4. Think about your bathroom's finishing touches(Think about the finishing touches for your bathroom and how they tie in with your fittings. If your space is small, consider using large tiles to make the room feel larger. Smaller, mosaic tiles are a great option if you want to draw the eye to a detail or make the room feel cosy.)
• 5. When using colour in a bathroom follow the 60-30-10 rule
  (The 60-30-10 rule is a good guide when using colour in the bathroom. 60% of the room should be your main colour, like white tiles on your wall and glazing on your bath or sink. 30% is your mid-range colour and is good for areas like the floor or vanity cabinet. 10% is your accent colour, a bold, punchy colour that you can add with your linen.)
• 6. Think about the positioning of towels rails and toilet roll holders(A final thing to consider is where you put your towel rails and toilet roll holder. Ideally, you want everything within easy reach. The towels should be close to the edge of the shower – and the heater if you have a cold winter. The toilet roll should be somewhere you can reach when you are sitting down.)

The following factors will effect the cost of renovating a bathroom

Size of the room
This is the very first thing that will impact the cost of renovating. As mentioned earlier the larger the room the more materials and labour required to complete it. A bathroom or laundry is a wet area in the home so that means waterproofing, plumbing, tiling, lighting, plus fixtures and fittings.

The breadth of renovations needed
Is the existing bathroom simply having everything replaced or are you considering moving a wall, changing the plumbing layout, altering the electrical outlets, adding a bath or even installing a new steam shower. The extent and complexity of the work required will lead to variations in costs due to the materials, time and expertise needed.

Materials and products
We all know you can go to Bunnings and buy a tap for $20 but you can also buy designer tap ware for $400. So of course the items you choose for floor tiling, vanity, sink, taps, drains, lighting etc will all lead to cost variances when renovating. Other options like under-floor heating, exhaust fan, heated towel rails can also be expensive items to purchase that can add a few thousand dollars to the budget needed. Cheap materials may not last as long as high quality items.

Who is doing what?
Labour is the largest cost to manage so if your renovation contractor uses lots of different sub-contractors or you make changes after work commences, then costs will increase. You may be able to save money by sourcing your own materials and ensuring everything is provided ready to be used by the tradespeople on site.

Hidden surprises
A variation to the agreed scope of renovation work may be required if something unexpected pops up. For example, when demolishing a room the contractors might discover asbestos and need that removed before continuing. Alternatively in older homes maybe the subfloor needs to be replaced due to water damage. Many of these things can’t be seen during initial inspections when quoting

For elderly usage, there are many other ways to make your bathroom facilities safer, including shower seats, grab bars, raised toilet seats or simply adding non-slip tiles and flooring to wet areas. Installation of a hand-held shower head can make it easier to control the water temperature and pressure

You can install a small sauna in your bathroom that will only take up about 10 square feet of space. Of course, if you have the possibility, you can also plan out a true wellness bathroom with a sauna.

Below describes some of the key considerations and explains the different types of saunas that are available.

Wood stove:
The crackling sound of the burning logs creates a very special atmosphere, and wood provides the dry heat typical of these saunas. However, a connection to the chimney needs to be a possibility, and the entire installation will need to comply with legal requirements for wood stoves. If you want to heat your bathroom sauna with a wood stove, it's best if this is planned for when the house is built.

Gas heater:
A bathroom sauna with a gas heater will come up to temperature very quickly. However, one of the main considerations here is ensuring proper ventilation for safety reasons. A sauna with a gas heater will also require a connection to the gas line.

Electric heater:
The simplest solution for a lot of bathrooms is probably a sauna with an electric heater since these are relatively easy and inexpensive to install. Unlike wood stoves and gas heaters, there are fewer safety risks in terms of ventilation, and they also carry a lower risk of fire. All you need is a high-voltage connection.

Infrared saunas:
An infrared sauna in your bathroom is not like a conventional sauna heater, but it fulfills a very similar function as a kind of relaxing "sweat lodge." Unlike electric heaters, a normal electrical connection is all you need here.

Shower sauna:
Modern steam showers are relatively easy to install, and they can be adapted to various conditions. The 2-in-1 solution can also – at least partially – help out if your bathroom has space constraints. Although these are not saunas in the classic sense, with the right equipment and infusions, they'll make you forget about having a "real" sauna in your
