To choose a custom shower curtain size, measure the finished width of the shower opening or curtain track and the vertical distance from the rod or track to the intended hem position. Add enough width for the curtain to gather or overlap at the sides, and choose a drop that helps contain water without dragging on the floor. Hotels, RVs, and hospitals often need different dimensions because their enclosures, installation hardware, and cleaning routines differ. A nominal 72 × 72 in curtain is a familiar retail reference, but it is not a reliable substitute for measuring the actual installation.

For a custom order, provide the opening width, required finished height, measurement units, hardware arrangement, and any material or edge-finish requirements. If the project includes multiple rooms or vehicle layouts, measure representative installations and confirm whether each one can use the same specification. Below, we explain a practical sizing process and the details buyers should confirm before requesting a quote.
Measure the usable span of the rod or track where the curtain will hang. For a straight installation, this is usually the distance between the end points that define the curtain’s travel, not necessarily the full wall-to-wall width. For an L-shaped or curved track, record the track path or provide a drawing so the supplier can understand how the curtain must cover the enclosure.
The curtain panel generally needs more width than the opening if it is expected to hang in folds or overlap at the edges. As a starting calculation, multiply the opening width by a fullness factor chosen for the desired appearance and coverage; a factor of 1.5 is an example, not a universal requirement. For an opening of 60 in, that example gives a finished panel width of 90 in before any special overlap or return requirements are added.
Measure vertically from the point where the curtain will hang, such as the rod or track, to the intended bottom edge. In a bathtub installation, the curtain may need to extend into the tub while remaining clear of the tub bottom; in a walk-in shower, it may need to finish near the shower base without resting on it. The appropriate clearance depends on the enclosure, water direction, and the facility’s operating preferences, so confirm the hem position on site.
For example, if the hanging point is 80 in above the intended hem position, the target finished height is approximately 80 in, subject to the way the curtain attaches to its hooks or carriers. Do not assume that the stated product height includes the distance from the rod to the top of the fabric. Ask whether dimensions refer to the fabric panel itself or to the installed curtain.
Confirm the attachment method before finalizing dimensions. Buttonholes, grommets, snap openings, hooks, and track carriers can affect the usable hanging height and the spacing of attachment points. If existing hardware must be reused, record its type and spacing, and share photos or a simple drawing with the supplier.
Also note whether the curtain needs a center opening, side overlap, split panels, a weighted hem, or a particular edge finish. These details can change how much coverage is needed even when the enclosure measurements are identical. For projects with unusual tracks, include the track shape and any fixed panels in the specification package.
Hotel projects often involve repeated installations, but room layouts may vary by floor, renovation phase, or room type. Measure each distinct shower or bathtub configuration and group rooms only when the rod or track dimensions and mounting heights match. A room schedule with one line per configuration helps purchasing teams avoid ordering a single size that does not fit every bathroom.
For replacement programs, compare the new measurements with an existing curtain only after checking how it was installed. A stretched, shortened, or incorrectly hung panel may not reflect the intended finished dimensions. Hotels should also state cleaning and replacement requirements so suppliers can discuss suitable materials and construction without assuming that one specification fits every property.
RV shower areas can have compact or non-rectangular layouts, and available space may be constrained by doors, fixtures, or curved tracks. Measure the actual track path and the vertical distance to the desired hem position rather than adapting a household curtain size. Check whether the curtain must clear a door, fold into a limited space, or fit around a fixed enclosure feature.

When ordering for multiple vehicle models, keep a separate dimension record for each model and production configuration. A modest difference in track shape or mounting height can change the required panel width or drop. If the curtain is part of a broader interior component package, share the adjacent profile or interface dimensions so the fit can be reviewed together.
Healthcare facilities may use shower curtains in different room layouts and may have cleaning, privacy, or maintenance requirements set by their own teams. Confirm the required dimensions with facilities management and infection-prevention or procurement stakeholders where applicable. Do not treat a curtain’s size or material description as proof that it meets a particular healthcare regulation or facility protocol.
For rooms with accessible layouts or specialized tracks, use the installed track dimensions and document any curtain opening or coverage requirements. If curtains are replaced on a schedule, label each size by room type or location to make future replenishment clearer. Verify that the selected attachment style works with the existing track and the facility’s handling procedures.
| Measurement | How to record it | Why it matters |
|---|---|---|
| Opening or track width | Measure the usable span or track path in inches or centimeters | Establishes the coverage area before fullness or overlap is considered |
| Finished panel width | Specify the fabric width before or after gathering, as agreed | Prevents confusion between flat dimensions and installed appearance |
| Finished height | Measure from the attachment point to the desired hem position | Helps the curtain fit the tub, shower base, or floor relationship |
| Attachment spacing | Record the count and center-to-center spacing of openings or carriers | Supports compatibility with existing rods and tracks |
Keep all dimensions in one unit system, or clearly show both inches and centimeters when needed. For reference, 1 in equals 2.54 cm; conversions should be checked before production, especially when dimensions include fractions. State an acceptable dimensional tolerance in the purchase specification rather than assuming that every supplier uses the same tolerance.
Custom sizing is only one part of the specification. Buyers should describe the intended use, cleaning process, desired opacity, color, attachment style, and whether the curtain is a single panel or a multi-panel arrangement. Material selection should be reviewed against the actual environment and the facility’s requirements, because performance depends on the material construction and conditions of use.
Ask suppliers to identify the offered material and explain relevant care instructions and construction options. If the project includes plastic profiles or related components, provide the interface dimensions and intended function so Huabao can discuss whether its plastic-profile capabilities are relevant to the broader assembly. This is especially useful when the curtain is being specified alongside a track, trim, or other customized component.
A clear request helps a supplier assess feasibility and provide a more useful quotation. Send the opening or track dimensions, target finished width and height, attachment details, material preferences, quantity, and delivery location. Add a drawing or photographs with a measuring reference when the enclosure is curved, unusually shaped, or part of a multi-room project.
Before confirming an order, ask the supplier to review the written dimensions and clarify whether quoted sizes refer to finished fabric or installed coverage. Confirm sample or approval procedures, packaging, production schedule, and any minimum order quantity directly, since these can vary by product and project. Keep the approved specification with the purchase records for repeat orders.
The right custom shower curtain size is determined by the installed opening, track shape, attachment method, and desired hem position. Hotels should organize dimensions by room configuration, RV buyers should measure each vehicle layout, and hospitals should confirm size and care requirements with the relevant facility teams. A nominal size can serve as a reference, but site measurements should guide the final specification.
As a next step, create a measurement sheet with width, height, units, hardware details, and any required finish or material information. Share it with Huabao to discuss the project and determine whether custom curtain specifications or related plastic-profile requirements can be supported. Clear measurements and written approvals make it easier to evaluate options and plan a consistent B2B order.
