Once your shower, or tub walls have been fitted with tile, granite, marble, onyx, or other hard surface material; we can perform the required onsite measure of your space. Our estimator has over 35 years of experience in this industry, and is in roughly 30 homes each week. He will collect all pertinent dimensions, verify proper horizontal surface slope, and check for level/plumb (or out of level/plumb) characteristics of your shower space. At that time he will also have a brief discussion with you, or your bathroom contractor, about what material details you would like for your enclosure, and answer any questions you may have. We will then provide you with a detailed, to the penny quote via email the next business day. Installation of your new enclosure will typically occur within 2 to 3 weeks from your order placement, depending on materials fabrication. If silicone sealant is needed; please wait a minimum of 10 hours before using your new heavy glass enclosure.
