Tile Drain Series: Center Pitch Installation
Threshold Installation (Fig 5 and 6)
For threshold installs, we recommend the drain run exactly
wall-to-wall to block any water from leaving the shower
or wet area. We do not recommend thinner or tile-in type
drains for threshold installations due to the lack of channel
width needed to sufficiently catch the water.
Infinity Drain Series that are
NOT recommended for threshold installation:
• S-AG 38 • FFDG 25
• S-DG 38 • FFAS 25
• S-TIFAS 65 • FFTIF 65
• S-TIF 65 • FTED 25
• S-TIFAS 99 • FTDG 25
• FXTIF 65 • FTAS 25
• FFED 25 • FTTIF 65
Barrier Free Installation (Fig 5 and 6)
Installing a shower drain without a curb, barrier, or
threshold creates a seamless look with easy accessibility to
the wet area. To achieve an ideal installation, floor heights
should be equal between the shower area (wet area),
outside the shower (dry area), and next room. Specific
conditions will determine what is involved. The FF and
FT offer the lowest overall heights (1 1/16” and 1 3/16”).
In addition, we offer a product (ST 65 - pg 76) to allow
channel to recess into subfloor an additional ¾” leaving
total height at 5/16”. The dry side of the shower should
have a slight pitch towards the linear system to ensure
proper drainage. The entire wet and dry floor area should
be waterproofed. Infinity Drain recommends working with
a licensed professional who is familiar with local codes and
installation requirements.
Center Pitch Installation (Fig 7)
A center pitch installation places the drain in the middle
of the wet area. The floor is pitched in four directions
towards the drain. The type of waterproofing used is
either the traditional method with a clamp down floor
drain, like Infinity Drain’s TD Series or a liquid/fabric sheet
membrane with a Bonded Flange drain body, like Infinity
Drain’s TDB Series.
