Space Considerations In Bathroom Design

When planning your bathroom, considering the available space is vital. You need to ensure your new bathtub can fit without compromising the rest of your bathroom layout.

Preparing For A New Bathtub

Before bringing a new bathtub into your space, preparation is crucial. Begin by measuring the bathroom area.

Check that the selected bathtub will fit the desired spot. Allow access for pipes and fixtures. Observe the current plumbing layout. Consider doorways and hallways for getting the tub into the room.

Dealing With Plumbing For Different Sizes

Plumbing needs differ for various bathtub sizes. Standard tubs typically measure 60 inches in length, but widths can range from 30 to 42 inches.

Larger or non-standard tubs may need different plumbing configurations. It’s essential to consult a professional for the best outcome.

  • Large tubs: Could need additional space and support. Ensure your hot water system can fill the larger volume.
  • Freestanding tubs: Offer more flexibility in placement but might need new plumbing lines.
