Section 1: Introduction 1.1 Steam Room Facts Who wouldn’t like to have a steam bath or steam shower in their own home? Steam provides an invigorating way to maintain or restore physical and mental health. Sitting in a steam room environment can help the body to burn calories, improve circulation, relax muscles, flush toxins from the body, cleanse pores, relieve stress, and help induce more relaxing sleep. All of this in just twenty minutes a day! The fact is; steam rooms and steam showers are becoming more and more common in home environments. They are no longer just for health clubs or the very wealthy; now anybody can own their own steam room. Steam room and steam showers are fairly often included in new home construction, rather than a standard shower. While there are many benefits to owning and using a steam room or steam shower there are also some basic principles that must be kept in mind when designing, installing and using these units: 1. Prevent steam from escaping.

9235 Waterproofing Membrane. Tile is the perfect finish for a steam room application and choosing the right tile is important. For best results, the tile should be impervious (i.e. porcelain) or have a glazed surface to help limit the amount of moisture and moisture vapor that makes its way into the system. An acceptable vapor barrier can be a vital component of any steam room and, when properly installed, can prevent moisture from getting into wall and ceiling cavities. When hot, moist air comes in contact with cooler surfaces (at or below dew point) it condenses and turns back into water. If the dew point temperature is within the wall cavity then the moisture will either build up within the wall or show up in areas where water is not supposed to be found. This can lead to structural damage, mold, water problems, poor indoor air quality, and more. In order to function properly it is critical that this vapor barrier laps into the shower pan (another critical component of a steam room installation).

2. Collect any condensed water and allow it to drain properly.

1.2 Tile Installations in Steam Room and Shower Applications Materials and Methods

3. Keep  water from dripping on the steam room occupants.

Let’s look at two typical steam room constructs:

Steam generation units create a great deal of moisture; this moisture initially takes the form of water vapor (steam). This water vapor is highly penetrative and any room not properly prepared may be exposed to damage caused by excessive moisture. Proper measures must be taken to prevent moisture transgression into or through walls, ceiling and floor.

1. The first design incorporates steel or wood framing and a concrete, slab-on-grade sub-floor. The ceiling should be sloped at least 2" minimum per foot (50 mm per 300 mm) to prevent water from dripping on steam room occupants (per Tile Council of North America recommendations). The floor should be pre-pitched (prior to the installation of the shower pan liner) at the rate of 1/4" per foot (6 mm per 300 mm) to make sure that water flows toward the drain. Keep in mind that a shower pan is required in all steam room/steam shower installations!

These preventive measures include a properly placed, suitable vapor barrier and/or an acceptable waterproofing membrane. LATICRETE International, Inc. always recommends using both a vapor barrier, placed on the framing or on the concrete/concrete masonry units prior to further construction, and LATICRETE® Hydro Ban™ or LATICRETE

Heading1:Here Section Introduction The installation begins with the proper choice and placement of a two-part clamping-ringstyle drain with weepers as per ASME A112.6.3. Place tile spacers or gravel around weep holes, as detailed by the design professional, to prevent mortar from clogging the weep holes and should be installed by a qualified plumber in accord with International Residential Code (IRC) P2709.4. The pipes and drain should be properly supported to prevent problems in the future. A suitable primary shower pan liner, complying with ASTM D 4068, D 4551 or other International Code Council (ICC) and International Association of Plumbing and Mechanical Officers (IAPMO) approved material, would then be installed to tie into the bottom flange of the drain (without blocking the weep holes). The liner must be turned up the walls to a point at least 3" (75 mm) above the top of the curb or 6" (150 mm) above the floor in steam rooms or steam showers without curbs. The shower pan must be properly formed and fastened to prevent problems. Check with local building code to help determine what shower pan liner is acceptable in your area. This pan will act as your vapor barrier on the floor. Curbs must be sloped to drain back into the steam room for condensation runoff. Perform a flood test to determine integrity of the pan liner and make repairs as necessary before proceeding. After the shower pan liner is in place, install the vapor barrier directly onto the side of the wall and ceiling framing that will be exposed to the steam room. The vapor barrier should be 4 – 6 mil thick polyethylene (cross laminated virgin polyethylene is excellent) and, if possible, should be one piece that can fit into the entire area. Fasten the vapor barrier to the studs with corrosion-resistant fasteners. A spot of LATICRETE® Latasil™ (100% silicone sealant) onto the fasteners will help prevent moisture penetration through the fastener holes. Make sure that the vapor barrier is properly formed and is tight to the studs of the walls and ceiling. Yes – the vapor barrier 10

must be installed onto the ceiling as well as the walls because steam can certainly escape through the ceiling. It is imperative that this vapor barrier be placed so that it laps into the shower pan liner! This way any moisture that comes in contact with the vapor barrier will drain into the shower pan and through the weep holes of the drain. Next, install a 2" (50 mm) thick (minimum) wire-reinforced, mortar bed comprised of LATICRETE 3701 Fortified Mortar Bed; or, LATICRETE 226 Thick Bed Mortar gauged with LATICRETE 3701 Mortar Admix onto the shower floor. The wire-reinforcement should be 2" x 2" (50 mm x 50 mm), 16 gauge, galvanized, welded wire mesh and should be placed at half the depth of the mortar bed. Make sure that the mortar bed maintains the 1/4" per foot (6 mm per 300 mm) slope to drain which was established by the pre-pitch in the sub-floor. After the mortar bed has cured, the installation of the cement backer board on the walls and ceiling can begin. The addition of a suitable insulation material between the wall and ceiling framing should be done before installation of the cement backer board. Insulation will help keep the heat in the steam room, cool air out, and helps to control the dew point (the temperature where condensation takes place) within the wall. The cement backer board used must be acceptable for steam room use and installed per the board manufacturer’s written installation instructions; this includes taping of all board joints. Use LATICRETE 254 Platinum and 2" (50 mm) wide, alkaliresistant fiberglass mesh tape to treat the board joints. Be sure to allow space at the ceiling/wall transition for the insertion of a slip joint to allow for proper expansion/ contraction to take place. Pipes and penetrations through board should be accounted for and space between board and penetration should be kept to a minimum. Allow the mortar used to tape the board joints to harden and then commence with

Tiled Steam Room and Steam Shower – Technical Design Manual

Section 1: Introduction waterproofing the entire inside area of the steam room with LATICRETE Hydro Ban™ or LATICRETE 9235 Waterproofing Membrane. The entire steam room should be waterproofed, including the ceiling, walls, floor, seat, and any other exposed area; this will help improve the functionality of the vapor barrier and inhibit the passage of most of the moisture through the system. Loop the LATICRETE Hydro Ban or LATICRETE 9235 Waterproofing Membrane into the slip joints to allow for movement in these areas. Any vapor transpiring through the LATICRETE 9235 Waterproofing Membrane should easily be handled by the vapor barrier. For more information on the installation of LATICRETE Hydro Ban or LATICRETE 9235 Waterproofing Membrane, please refer to www.laticrete.com. Make sure that ANY and ALL penetrations are properly waterproofed and sealed tightly with LATICRETE Latasil! Tile can be installed directly onto the LATICRETE Hydro Ban or LATICRETE 9235 Waterproofing Membrane as soon as it is dry to the touch. LATICRETE 254 Platinum is the thin-set of choice for steam room/ steam shower installations. Check with the manufacturer of the tile to make sure that it is compatible in steam room applications.

2. The second design involves installation over all other substrates including concrete or masonry walls. Again, the ceiling should be sloped at least 2" minimum per foot (50 mm per 300 mm) to prevent water from dripping on steam room occupants (per Tile Council of North America recommendations). The floor should be pre-pitched (prior to the installation of the shower pan) at the rate of 1/4" per foot (6 mm per 300 mm) to make sure that water flows toward the drain. Also, a shower pan is required in ALL steam room/steam shower installations! The installation begins with the proper choice and placement of a two-part clamping ring style drains with weepers as per ASME A112.6.3. Place tile spacers or gravel around weep holes, as detailed by the design professional, to prevent mortar from clogging the weep holes, they should be installed by a qualified plumber in accord with IRC P2709.4. The pipes and drain should be properly supported to prevent problems in the future. For this type of steam room construction, LATICRETE Hydro Ban or LATICRETE 9235 Waterproofing Membrane can be used as the primary shower pan liner. A suitable primary shower pan liner material, complying with

Once the tiles have set firm, grout the installation with LATICRETE SpectraLOCK®† PRO Grout for best performance. Alternative grouting choices would be LATICRETE PermaColor™ Grout^. Use LATICRETE Latasil, with LATICRETE 9118 Primer, in slip joints, steam jets, movement joints, around the drain, to seal lighting fixtures, access panels (if present), or at any change of plane.
