When constructing a new shower for your bathroom, installing the shower door is one of the final stages. Provided all preceding construction work has been executed flawlessly, the shower door will effortlessly swing or slide open, close with precision, and effectively contain all the water within the shower enclosure. However, rectifying the prior work becomes a formidable challenge if you miscalculate the measurements. Acquiring standard rough-in door sizes will ensure a seamless and impeccable installation process.
Pivot or Swinging Shower Door Sizes
Most pivot or swinging shower door units come in a standard width of 48 inches, offering ample space for entry. The walk-in door opening within these units typically measures approximately 26 1/2 inches in width, ensuring convenient access.
Sliding Shower Door Sizes
When it comes to sliding shower door units, the standard width tends to be 60 inches, providing a generous enclosure for your shower space. The actual walk-in door opening in these units ranges from approximately 22 inches to 25-3/8 inches in width, catering to various design preferences and shower requirements.
Bypass Door Sizes
When it comes to sliding shower doors, they come in various sizes. The narrower ones typically range from 45 to 47 inches in width, while wider sliding shower doors can measure between 57 and 59 inches across. In terms of height, most shower doors stand at 79 inches tall.
Alcove shower/bathtubs are commonly 60 inches wide, and their bypass or sliding doors usually measure around 58 inches in width. When framing the nook, it’s crucial to leave space to accommodate the shower/tub; it must be precisely 60 inches.
This measurement may involve a direct-to-stud configuration or exist between two wall coverings. Direct-to-stud installation refers to a pre-fabricated unit with coordinating surround walls that securely attach to the bare wall studs. While the three walls surrounding the alcove are framed, no water-resistant wallboard or cement board is installed over the studs. Consequently, in this type of installation, the actual dimensions of the shower/bathtub are slightly less than 60 inches, often hovering around 59 7/8 inches. However, this gap can vary slightly depending on the manufacturer. In contrast, other alcove installations feature wall coverings like drywall or cement board on the studs.
There is a metal frame on both the left and right sides of the shower door. This frame, along with the need for a slight space on each side of the shower door, reduces the overall width of the shower door in these 60-inch alcove scenarios to 58 inches.
Frameless Pivot (Swinging) Shower Door Sizes
Frameless pivot or swinging shower doors offer versatility in size to accommodate a range of bathroom layouts. These doors are available in three standard-width options:
39 1/8 inches to 44 inches: This size range is ideal for bathrooms with narrower shower enclosures, providing a sleek, space-saving solution.
27 5/16 inches to 31 1/8 inches: For compact bathrooms or shower spaces, these smaller frameless pivot shower doors offer an efficient way to maximize your available area while maintaining a stylish design.
43 1/8 inches to 48 inches: If you have a spacious shower area and prefer a more open and luxurious feel, these wider frameless pivot shower doors are an excellent choice, ensuring a comfortable and inviting showering experience.
How to Measure for a Shower Door
When measuring for a shower door, whether it’s for a standalone shower or a shower/bathtub combination, follow these steps:
- Width Measurement: Use a tape measure or a laser measuring device to measure the width of the opening from one side to the other. Take measurements at two points: one at the top and one at the bottom. It’s essential to measure in two places because walls and alcove enclosures can warp over time or may have been initially constructed slightly out of square. Select the larger of the two width measurements and round up to the nearest 1/8 of an inch.
- Height Measurement: To measure the height, start from the side of the bathtub or shower curb for showers. Like the width, measure at two locations: once on the left and once on the right. Again, choose the larger of the two height measurements and round up to the nearest 1/8 of an inch.
Remember that when you install shower doors and their frames, there is some flexibility to accommodate walls that may be slightly out of square. However, obtaining these measurements as accurately as possible is crucial to ensure a proper fit during installation.
