Create an Open Concept Shower with Large Pans

When designing a new bathroom or renovating an existing space, installing an open concept walk-in shower can provide an accessible and inviting option for bathing. Key to maximizing both aesthetics and functionality in these spacious showers is choosing the right extra large shower pan.

Determine Your Shower Size Needs

The first consideration when looking at large shower pans is identifying how much interior space you require. Areas to evaluate when making this determination include:

• Number of intended users - Will this primarily be a private shower or shared bathing area?
• Accessibility requirements - Do any household members need ADA compliant handles or wheelchair clearance?
• Available space - What are the maximum workable dimensions based on existing bathroom layout?

Once intended shower users and preliminary sizing needs are determined, you can zero in on specific extra large shower pan dimensions that align with your plans.

Choose Between Center Drain vs Linear Drain Pans

Most oversized shower pans are available in configurations with either a center drain or linear drain design. Key factors in determining the optimal drain placement include:

• Ease of access - Center drains allow equal entry from all sides.
• Slope efficiency - Both center and linear drains can be engineered for efficient water direction.
• Aesthetics - Linear drains create a modern, spa-like look.

Additionally, linear drains provide more flexibility when using partial partitions or specific shower door placements whereas center drains maximize open concept layouts. Consider existing plumbing locations and intended shower design elements when deciding between the two drain options.

Select Ideal Shower Pan Materials

Oversized shower pans are commonly constructed using tile, acrylic, solid surface materials or a combination of products. Evaluate the advantages and drawbacks of each when selecting the ideal material choice:

• Tile: Extremely durable and waterproof, provides classic appearance
• Acrylic: Budget-friendly, scratch resistant surface
• Solid Surface: Non-porous for stain resistance, seamless look, expensive
• Composite: Combines acrylic surface with mortar or foam base reinforcement

Keep in mind that larger shower pans place more weight load demands on the underlying materials. Mortar reinforced tile and solid surface pans provide the greatest strength and crack prevention for bigger sizes.

Measure Carefully and Confirm Dimensions

With measurements of your available space in hand, match those dimensions against sizing options offered by reputable oversized shower pan manufacturers. Be sure to request and carefully vet any technical drawings that outline:

• Interior floor area dimensions
• Threshold height
• Drain style and location
• Built-in slope degree

Confirm that the chosen shower pan size allows for a 1/4" clearance between the edges of the pan and walls or partitions. This gap is required for proper caulking.Pan dimensions that exceed maximum workable openings can prevent installation.

Understand Weight Load and Reinforcement Needs

In addition to verifying dimensional suitability, be sure your flooring subsurface can accommodate the weight of a large format shower pan once filled with water. Typical load guidelines per square foot are:

Heavier tile and stone pans may require additional floor joist support using cross beams or sister joists. Your contractor should assess load capacity needs specific to the materials selected.

Prepare the Installation Surface Properly

Preparing the shower stall subsurface appropriately ensures proper drainage slope and a solid underlayment that won't crack or shift under weight. Key elements involve:

• Gutting existing surfaces down to bare structural framing
• Confirming framing is level and plumb
• Installing cement board on walls and floor
• Applying pitched mortar bed aligned with drain location

Waterproofing the subsurface beneath a large shower pan provides vital moisture protection. Tanking liquid membranes that seal concrete board surfaces offer the most secure barrier.

Follow Manufacturer's Installation Instructions

Reputable oversized shower pan suppliers provide detailed guides outlining proper installation techniques. Key steps when physically setting the pan involve:

• Applying recommended adhesive or mortar
• Carefully lowering and leveling the pan
• Anchoring the pan securely in place
• Caulking all edges and seams

Strictly adhere to direction regarding approved adhesives and the precise order of operations. Rushing this vital part of the process compromises safety and functionality.

Customize with Accessories Like Seats or Grab Bars

Large shower pans provide ample room for built-in seating, assist bars, shelves and other helpful accessories. When planning accessory placement, consider:

• User mobility and reach
• Compliance with ADA standards
• Convenience for all household members

Contrasting bright colors on accessories against neutral pan and wall tile provides an appealing look while aiding visibility. These custom details give your open shower concept personalized style.

Choose Complementary Wall Surrounds

The walls surrounding any shower pan serve both functional and aesthetic purposes. When selecting wall finishes:

• Favor waterproof, non-porous tile or solid surface panels
• Extend materials into recesses housing shelves or benches
• Use matching grout and caulk for smooth transitions

Carrying wall materials overhead, using shampoo niches and avoiding seams over large format pans prevents potential moisture issues.

Coordinate Plumbing Fixtures and Lighting

With pan drainage and basic surround materials decided, shift focus to plumbing and lighting needs by:

• Selecting showerhead style and positioning for spray coverage
• Placing fixtures to align with water supply and drain lines
• Incorporating both ambient and task oriented lighting

Handheld showerheads and adjustable body sprays give user flexibility. Positioning lighting to avoid shining directly in bather's eyes or casting shadows over thresholds promotes safety.

Installing an oversized shower pan allows you to create an accessible, spa-like walk-in shower perfectly tailored to your space and needs. Advance planning for critical factors like dimensions, drain configuration, material selection and custom accessories ensures optimal form and function.

By following essential preparation steps and manufacturer's installation directions, an extra large shower pan can serve as the centerpiece of an inviting, open concept bathing area you'll enjoy for years to come.
