The DoubleSil Shower Door Installation Method
Just Retiled Your Shower? Finish It the Right Way.
Your new tile deserves shower glass that is measured accurately, installed carefully, and secured with attention to the areas hidden behind the hardware. Every applicable shower door installation in Sarasota from Shower Doors of Sarasota includes our exclusive DoubleSil method—a layered sealing and anchoring process designed to help protect drilled attachment points from moisture intrusion behind tile and walls.

The Hidden Details
Why Drilled Shower-Door Attachment Points Matter
The Most Important Installation Details Are Often Hidden
Hinges, clamps, channels, and other shower-glass hardware may require carefully positioned holes through finished tile. Once the hardware is installed, the attachment point is no longer visible—but it remains close to daily water exposure.
That is why we do not treat drilled holes as an ordinary installation step. DoubleSil adds a deliberate sealing sequence before and during hardware installation, helping protect the opening within the tile as well as the completed hardware-to-tile connection.

Step by Step
How the DoubleSil Installation Method Works
DoubleSil is the installation method used by Shower Doors of Sarasota, designed to help protect tiled shower surfaces by sealing the mounting point at multiple stages of the installation process. Each stage below builds on the last—click any illustration to view it larger.
Step 01: Precision Drilling
We carefully measure each hardware location and drill the hole exactly where it needs to go. Precise placement helps ensure proper alignment while minimizing unnecessary penetrations through the finished tile.
Step 02: Primary Internal Seal
The drilled hole is filled with sealant before the wall anchor is installed. This creates the first protective barrier inside the tile penetration, where moisture could otherwise travel behind the finished shower surface.
Step 03: Sealed Wall Anchor Installation
The wall anchor is inserted directly into the sealant-filled hole. The anchor fits tightly within the opening, gives the metal screw a secure material to grip and thread into, and helps reduce direct pressure from the screw against the tile. This supports a stronger installation while helping protect the tile from cracking or damage.
Step 04: Secondary Internal Seal
A second application of sealant is placed directly inside the wall anchor. This adds another protective layer within the mounting point before the screw and hardware are installed.
Step 05: Stainless-Steel Fastening
We use stainless-steel, rust-resistant screws to securely fasten the shower hardware to the tiled surface. As the screw is tightened, it compresses the sealant and pushes it into the small spaces surrounding the screw, anchor, and drilled opening. This helps fully seal the penetration and reduce the possibility of water reaching the area behind the tile.
- The Result
The Finished DoubleSil Protection System
The completed DoubleSil installation combines sealant inside the drilled hole, a tightly fitted wall anchor, a second seal inside the anchor, and a stainless-steel fastener. Together, these layers create a secure, professionally finished mounting point designed to help protect the area behind the tile from future moisture intrusion.

DoubleSil creates protection in stages—within the drilled opening and again at the completed hardware connection.
The DoubleSil Difference
Added Protection Where It Matters Most
Layered Seal Protection
The process addresses both the prepared opening and the completed hardware connection — two sealing stages that protect different portions of the attachment point.
Protection at Critical Attachment Points
Drilled locations receive additional attention because they bring tile, hardware, fasteners, and water exposure together in one place.
Helps Reduce Moisture Intrusion
DoubleSil is designed to help reduce the risk of moisture entering behind tile at applicable drilled attachment points.

Our team carefully measures the opening, reviews the hardware layout, explains the available options, and uses the DoubleSil method at applicable drilled locations. It is one more way we provide homeowners with confidence in both the visible result and the details behind the hardware. Whether you are considering swinging shower doors, sliding shower doors, or stationary glass panels, professional shower glass installation after tile is where DoubleSil earns its place.

Common Questions
Frequently Asked Questions About DoubleSil
No frameless shower enclosure should be described as completely waterproof. Frameless systems have functional gaps around doors and panels. DoubleSil specifically addresses applicable drilled hardware attachment points and is designed to help reduce the risk of moisture entering behind the tile at those locations.
Drilled openings create attachment points for hinges, clamps, channels, and other hardware. Because these areas may be exposed to water, careful preparation, sealing, anchoring, and fastening are important parts of the installation.
Exterior finishing sealant addresses the visible hardware-to-tile connection. DoubleSil also incorporates protection within the drilled opening before the anchor and fastener are fully installed, creating a layered approach rather than relying only on the visible exterior seal.
No. DoubleSil is included with applicable shower-door installations performed by Shower Doors of Sarasota.
Drilling requirements depend on the shower layout, hardware, wall construction, and glass system. During measurement and planning, our team determines the appropriate attachment method and explains the proposed hardware locations.
Drilling through finished tile requires proper tools, careful layout, and professional technique. Our team evaluates the proposed hardware locations and carefully drills only where required for the selected glass system.
The shower should generally be measured after the tile, curb, thresholds, and other finished surfaces affecting the glass dimensions are completed. We like to measure once tile and waterproofing are fully cured, then fabricate and install your enclosure.
No installation method can guarantee against every possible source of water intrusion or damage. DoubleSil is an added installation precaution designed to help protect drilled attachment points when shower-glass hardware is installed through tile.
