Design Considerations For Your Shower

Planning your dream shower involves key choices. From aesthetics to functionality, every detail matters. Your shower impacts daily routines. Let’s dive into important factors for a well-planned shower space.

Choosing The Right Shower Type

Shower types vary widely, from elite walk-ins to multi-functional units. Consider the space available. Think about who will use the shower. Will it need to cater to different heights or accessibility needs?

  • Walk-in Showers: Sleek and accessible, but need more space.
  • Tub/Shower Combos: Great for families, offering versatility.
  • Corner Showers: Save space in small bathrooms.
  • Shower Panels: Equip with various jets and sprays for luxury.

Understanding Water Pressure And Flow Rates

Water pressure and flow rates matter for a good shower experience. Check existing plumbing for pressure levels.

Pressure Level Flow Rate Shower Experience
Low < 1.5 GPM Gentle, adequate for basic needs.
Medium 1.5 – 3 GPM Comfortable, balanced for comfort.
High > 3 GPM Powerful, optimal for luxurious feel.

A plumber can assess your home’s capability. They ensure your chosen type matches the water pressure. Some may need a pump to increase flow rates. A balanced shower valve might be necessary for stable temperature, even when other taps are in use.
