Showers Systems – TECH 2015

showersystemsShower systems are streamlining the installation of showers and steam showers with a range of developments such as: curbless/barrier-free systems for accessibility, flexibility and style; pre-formed components for speed of installation and shower integrity; fool-proof waterproofing and aesthetic advances like linear and wall drains.

For instance, Fin Pan’s Jeff Ketterer pointed out that many shower designs now offer curb…less appeal! “Many homeowners are choosing to remove the bathtub and replace it with walk-in showers that create a spa-like atmosphere. The entrance in a curbless shower is flat and flush with the bathroom floor, leaving a smooth transition into and out of the shower. The combination of style and accessibility provides greater value to a bathroom.”

While a fashion statement, curbless showers also offer practical advantages for disabled or aging populations. Ketterer said that according to the Administration on Aging, “For the next 18 years, baby-boomers will be turning 65 at a rate of 10,000 per day. Of these, 79% report the ability to age-in-place and live independently as their main concern.” The availability of “new and innovative curbless shower systems that require no structural modifications to the floor joists as was required in the past can meet everyone’s needs by offering style, accessibility and unlimited design options at every stage of life,” Ketterer said.

Following are a sampling of technological directions in shower systems for contractors to consider.  – Lesley Goddin

Barrier-free showers are continuing as not only a trend for an aging population but a fashion statement and design element. Having the ability to build a barrier-free shower in any configuration is most popular. The marriage of traditional methods and new technology continues its push into the market. This is being driven by the building code that recently reiterated that joists are not to be modified more than 1/4” unless a structural engineer is consulted. A contractor assumes the structural liability if they compromise the joist structure without engineering consultation. In many homes that were built with engineered joists in the 2000s, the addition of a barrier-free shower or even traditional mud pan was prohibited by the engineered joist. New methods have made installation of shower products possible in engineered joist construction.

Luxurious bathrooms have been a residential trend, but now owners of larger multi-unit buildings are also demanding custom-looking showers. Spa-like bathrooms have recently become more prominent in institutional, healthcare, resort, spa and pool facilities. Owners of commercial and residential spaces rely on the contractor to help them create these spa-like sanctuaries. These rooms have to blend form and function, combining a shower’s necessary utility with the look and feel of a spa.

However, in order to keep profits up, contractors need to work efficiently – particularly on multi-unit jobs. Preformed products – like niches, shower seats and curbs – help contractors meet the demands of this design trend.

Preformed components are consistent and easy to install – great for fast multi-unit installations. Look for preformed components that integrate seamlessly with existing surface prep solutions, mortar, tile and grout. For protection against mold and mildew, choose a product that comes coated with an IAPMO- approved, waterproof membrane that meets ANSI A118.10. Preformed components are a great way for tile installers to add a design element that fits with today’s building trends.

Barrier-free shower installations are gaining popularity for their clean-looking tile lines and zero-entry profiles. In order to properly execute these installations without the benefit of a traditional curb placed at the shower entry, high-tech installation materials and drains can be used.

Possibly the best current installation methods/options for barrier-free shower applications are the Tile Council of North America’s (TCNA) B-422-14 method or a modified version of B-415-14. This installation method provides a complete waterproof connection between the waterproofing membrane and the drain placed at the surface of the tile installation – which minimizes the height of the overall installation. Therefore, there is no need for the full, bulky 1-1/4” to 2” (31mm to 50mm) thick mortar bed and curb that are required in traditional shower pan installations.

This barrier-free installation type places the waterproofing membrane underneath the tile or stone finish versus the bottom of the mortar bed in traditional shower-pan applications. These methods allow water to shed right at the surface through an integrated bonding flange type drain system or a linear drain with a bonding lip, which receives the waterproofing membrane.

The slope in the shower assembly can be started from a much lower profile while still maintaining a 1/4” per foot (6mm per 300mm) slope. These assemblies provide a dramatic improvement when compared to the traditional, bulky, thick-bed mortar installation systems.

In response to a rapidly escalating growth in demand, several companies have introduced linear drains. These drains have been popular in Europe for years because they complement contemporary and barrier-free designs. The single slope created with a linear drain allows for the use of large format tiles that are ideal for contemporary, barrier-free showers favored by designers.

A number of linear drains are available. Some are systems that include waterproofing membranes. Other manufacturers offer only the drain and suggest options for waterproofing.

Things you should consider when selecting a drain include:

  • Does the drain meet code requirements (not all do?)
  • Does it assure a secure, watertight connection between the waterproofing membrane and the drain?
  • Does it offer the aesthetics desired? Because in the end, the strainer is all you will see.

The trends in our sector of the industry are very simple and clear:

1. Curbless showers mean true zero entry

2. Linear drains spanning the full width of the shower without dead spots on the ends of the drains

3. Use of single-pitch shower pans made of 100% recycled materials

4. Integration with shower-pan accessories and waterproofing for speed and ease of installation.

5. A new trend is moving the drain into the wall instead of floor.

CONTRACTOR PERSPECTIVE: 

SHOWER SYSTEM

owenShower systems/drain systems seem to be popular with architects in hotels now and I imagine the trend will continue to grow. These shower systems come complete with pre-sloped shower pans, pre-formed curbs, waterproofing membrane, corners, seam rolls, etc.  

These are now being specified because they are a more efficient/effective method than the traditional way that entailed building the curb out of bricks, etc. However, it’s still necessary to have skilled tradespeople who have been trained to install these systems. Problems can still occur and skilled tradespeople best know how to address them. 

For example, the assumption is that since you simply install the pre-slope onto the substrate, and because the pre-slope already has a pitch of 1/8” per foot to the drain, you will have guaranteed drainage, no worries.  Well, there could be a worry if the slab the installer was given is out of level 1/4” per foot in the opposite direction of the drain and this is not addressed. Due to field imperfections like this, there will always be the need for a trained craftsperson to do the install. Skilled tile craftspeople have the necessary experience and knowledge, and know what to look for and how to deal with circumstances like this.

quickdrain-showerQuick Drain USA has introduced a brand new concept in the evolution of shower drains: the elegant WallDrain system that takes the idea of linear drains to a logical conclusion -– no drain in the shower floor at all! This allows sloping of the whole shower pan in one direction to eliminate any grates and covers to step on or clean. This simple idea is mostly used in wet rooms and curbless showers. The system has full height, depth and length adjustability built in for ease of installation and perfect look every time.
