Project Description



When renovating your bathroom there are a number of key design points to consider. The team at Style Plus | Renovations Auckland take a look at four of the common bathroom renovation and design topics;

  • Waterproofing.
  • What is a Producer Statement?
  • Tiling Design.

Once the plasterboard’s finished and the internal wall and ceiling linings are all sorted, it’s time for the bathroom area to be waterproofed. Proper waterproofing in wet areas is absolutely vital – water leaking into floor and wall spaces can very easily rot structural timbers and do some heartbreaking damage to a house.

Bathrooms are, by nature, wet spaces. Properly detailed and installed waterproofing is essential behind tiled surfaces with cement-based grouts as tiling is not inherently waterproof. At Style Plus we regularly see during a bathroom renovation, failure of tiled surfaces – it’s a common problem in New Zealand.


Building Code clause E3 Internal moisture requires buildings to be constructed to avoid fungal growth on linings, water overflowing to adjoining units and moisture damage to building elements. The ‘Acceptable Solution E3/AS1’ does not specifically define a wet area, but uses the terms ‘subject to watersplash’ and ‘showers’ when defining wet area requirements.

Referring to E3/AS1, a waterproofing membrane is required for tiled shower enclosures where tiles are laid over an absorbent substrate such as fibre-cement or water-resistant plasterboard. Suitable finishes for wet areas are:

  • Timber and timber-based materials, such as timber strip and overlay flooring, particleboard or plywood, if they are sealed with a waterproof applied coating.
  • Compressed sheet (fibre-cement) used as a substrate.
  • Waterproof sheet material such as vinyl.
  • Terrazzo, concrete or cement plaster with steel trowel or polished finish.
  • Ceramic and stone tiles with 6% maximum absorption (joints must be waterproof and bedding material specified as suitable for wet area use).
  • Cork tile or sheet with a waterproof coating and sealed joints.


Style Plus is a Registered Waterproofing Applicator, for E3 “Internal moisture standards NZ” we only use Mapei’s brand’s approved “impervious membrane systems”. This is a ready-to-use, ultra quick-drying, flexible liquid membrane for internal waterproofing.

Style Plus is also listed as an approved “Producer Statement Author” for Auckland City Council .We can take care of all the regulatory requirements on your behalf, such as requesting “Waterproofing Inspections” , submitting detailed documentation regarding the products we use and working with councils on unusual tiling requests which gives you, the customer, peace of mind that we stand by our installation.

Having full support from the manufacturers & councils, who we regularly liaise with, we can take care of all your waterproofing requirements, which include but not limited to bath cradles, wet floor showers, laundries and kitchens.

A Producer Statement is a statement expressing the author’s view that plans, specifications, or completed works comply with the technical requirements to satisfy some or all requirements of the Building Code. A Producer Statement will usually be issued by a recognised specialist, for example, an engineer, architect or competent contractor such as Style Plus.

For waterproofing, the waterproofing membrane warranties and installation producer statement (PS3) are required once the job is completed. These documents may be required to be provided during the renovation process as part of the quality assurance process and prior to the issue of the Code Compliance Certificate (CCC).

When considering your bathroom renovation or new build project, there are a number of types of tiling to choose from, and quite an array of sizes, shapes and colours. The type of tiles you select will depend on a couple of key factors:

  • Style of your interior design.
  • Your colour scheme.
  • Your space.
  • Your bathroom fixtures.

The way you place your tiles can have an effect on the light and sense of space in your new bathroom. An example would be to use a reflective tile surface to bounce light around the room or by using long horizontal tiles to help make walls appear wider.


Ceramic tiles are composed of clay, water and minerals, and are made by baking in a kiln. This type of tile comes in an vast range of styles and colours, however, they can be fragile and porous if unglazed. The type of glaze not only affects the final finish and look of the tile but provides an amount of absorption prevention and strengthens the tile against breaking or chipping. Ceramic tiles can range in price, but are usually a cheaper choice over other tiling options.


As the porcelain are denser in composition, they tend to be longer lasting and more hard wearing. The colouring of a porcelain tile goes all the way through rather than simply being painted onto the surface, so the tones tend to be fuller and richer. This is a benefit if you do end up chipping a tile, as it won’t be as noticeable as it would on a ceramic tile. Of course, all these aspects make porcelain tiles a little more expensive, but in terms of quality and longevity, the price is usually worth it.


These types of tiles allow you to create an intricate effect or pattern in a range of colours and styles. Although squares are the most common variety, it is also possible to find mosaic tiles in other shape, including octagons, hexagons, rectangles and triangles. Some mosaic tiles come mounted onto a mesh for ease of application, but this can limit configuration options when you’re using several different coloured tiles. Mosaics provide a striking feature in any bathroom, though it’s best to use them minimally if you have chosen a bright or bold colour, reserving them for a bath backsplash or shower area.


Marble is a traditional and versatile stone that works beautifully for bathroom floor and wall tiling. The pros to using Marble tiles are obvious, it is absolutely gorgeous! The cons are that it is quite slick, and scratches easily. The good thing about scratches on Marble, as opposed to ceramic tile, is that scratches and chips can be ‘buffed out’ of Marble. So if you have an accident, you can buff it out and it will look brand new. Marble is available in several different tones, and is suitable for other surfaces as well as tiling.


There are a variety of other natural stone tiling options, including granite, slate, travertine, onyx and sandstone. All of these have their own unique appearances and colours, from stunning purple slate to creamy travertine. Granite is a fantastic choice for both bathrooms and kitchens (and is most commonly used for luxury kitchen worktops). Granite bathroom tiles are naturally antibacterial and are not damaged by water, making them perfect for heavy use in a wet room, for example. Sandstone has a grainy surface and feels warmer to the touch than many other tiles, making it ideal for bathroom flooring to give an inviting rustic appeal.
