DIY Hot Mop Shower: The Ultimate Guide You Need to Know

Crafting Your Own DIY Hot Mop Shower: A Comprehensive Guide

Building a diy hot mop shower can seem daunting, but with the right planning and execution, you can create a beautiful and waterproof shower pan. This guide breaks down the process, offering clear steps and helpful advice to empower you to tackle this project yourself.

Understanding the Hot Mop Shower System

Before diving in, let’s understand what makes a diy hot mop shower unique and why it’s a reliable waterproofing method.

What is a Hot Mop Shower?

A hot mop shower utilizes layers of hot asphalt and roofing felt to create a seamless, waterproof membrane directly on the shower subfloor. This robust waterproofing is then covered with a mortar bed and tile. Think of it as a "bathtub" built directly into your shower floor.

Why Choose a DIY Hot Mop Shower?

• Reliable Waterproofing: The multi-layered asphalt creates a continuous barrier against water penetration.
• Longevity: When properly installed, a hot mop shower can last for decades.
• Cost-Effective: Compared to some modern waterproofing systems, the materials can be more affordable.
• Customizable: You have complete control over the shower pan’s size and shape.

Planning Your DIY Hot Mop Shower Project

Careful planning is paramount to a successful diy hot mop shower installation. This stage involves assessing the area, gathering materials, and understanding local codes.

Assessing Your Shower Area

1. Inspect the Subfloor: Ensure the subfloor is structurally sound and free of rot or damage. Replace any compromised areas.
2. Measure the Shower Area: Accurately measure the dimensions of your shower floor to determine the amount of materials needed. Consider the finished slope for drainage.
3. Plan for the Drain: Determine the type and location of your shower drain. Ensure proper compatibility with the hot mop system.

Gathering Materials and Tools

Here’s a comprehensive list of materials you’ll need for your diy hot mop shower.

Material	Quantity	Notes
Roofing Felt (15 lb or 30 lb)	Varies	Based on shower size; purchase extra.
Hot Asphalt	Varies	Type 3 asphalt is commonly used; consult with a professional supplier.
2×4 Lumber	Varies	For creating the dam around the shower area.
Mortar Mix	Varies	For creating the shower pan slope after the hot mop.
Tile & Grout	Varies	Your choice of tile and grout for the finished shower floor.
Metal Lath	Varies	To help bond the mortar bed to the hot mop surface.
Fasteners (nails, screws)	Varies	For securing the lumber.

You’ll also need specialized tools:

• Mop Pot: For heating the asphalt. Renting is often the best option.
• Mops: Long-handled mops designed for applying hot asphalt.
• Propane Torch: For heating seams and corners.
• Gloves (Heat-Resistant): Essential for safety when working with hot asphalt.
• Safety Glasses: Protect your eyes from splashes and fumes.
• Respirator: Protect your lungs from asphalt fumes.
• Utility Knife: For cutting roofing felt.
• Measuring Tape: For accurate measurements.
• Trowel: For applying mortar.
• Level: To ensure proper slope.

Understanding Local Codes and Regulations

• Check with Your Local Building Department: Research local building codes and regulations regarding hot mop showers. Permits may be required.
• Professional Consultation: If you are unsure about any aspect of the project, consult with a licensed plumber or contractor.

Installing Your DIY Hot Mop Shower

With careful planning completed, you can now begin the installation process for your diy hot mop shower.

Preparing the Shower Area

1. Install the Shower Drain: Connect the drain to the plumbing according to the manufacturer’s instructions.
2. Build the Dam: Construct a dam around the shower area using 2×4 lumber. This will contain the hot asphalt and create the necessary height for the shower pan. Ensure the dam is securely fastened to the subfloor.
3. Clean the Subfloor: Thoroughly clean the subfloor to remove any debris, dirt, or grease.

Applying the Hot Mop

Safety is paramount during this stage. Always wear appropriate protective gear, including heat-resistant gloves, safety glasses, and a respirator. Work in a well-ventilated area.

1. Heating the Asphalt: Carefully heat the asphalt in the mop pot according to the manufacturer’s instructions. Monitor the temperature closely to prevent overheating.
2. Applying the First Layer of Felt: Start at the drain and work outwards, overlapping the felt by at least 4 inches. Use the hot mop to saturate the felt with asphalt, ensuring a strong bond to the subfloor and dam.
3. Applying Subsequent Layers: Apply two to three more layers of roofing felt, each overlapping the previous layer. Ensure each layer is fully saturated with hot asphalt. Pay close attention to corners and seams, using a propane torch to heat and seal any gaps.
4. Inspect the Hot Mop: After the asphalt has cooled, carefully inspect the hot mop for any cracks, holes, or weak spots. Patch any imperfections with additional felt and asphalt.

Creating the Mortar Bed

1. Install Metal Lath: Staple metal lath to the top of the hot mop surface. This will provide a better bond for the mortar bed.
2. Mix the Mortar: Mix the mortar according to the manufacturer’s instructions.
3. Apply the Mortar Bed: Apply the mortar bed, creating a slope towards the drain. Use a level to ensure the slope is consistent and adequate for proper drainage. A typical slope is ¼ inch per foot.
4. Cure the Mortar Bed: Allow the mortar bed to cure completely according to the manufacturer’s instructions.

Tiling Your Shower Floor

1. Prepare the Mortar Bed: Clean the cured mortar bed and apply a thin-set mortar according to the manufacturer’s instructions.
2. Install the Tile: Carefully install the tile, ensuring proper spacing and alignment.
3. Grout the Tile: Once the tile is set, grout the joints and clean the excess grout.

Important Safety Considerations

• Ventilation: Ensure adequate ventilation when working with hot asphalt. Fumes can be harmful.
• Protective Gear: Always wear appropriate protective gear, including heat-resistant gloves, safety glasses, and a respirator.
• Fire Safety: Have a fire extinguisher readily available. Keep flammable materials away from the hot asphalt.
• Professional Help: If you are uncomfortable with any aspect of the project, consult with a licensed plumber or contractor.
