Guide to Custom Shower Curtain Sizes for Hotels, RVs, and Hospitals

There is no single custom shower curtain size that works for every hotel, RV, or hospital. We recommend measuring the installed opening, deciding how much side coverage and overlap you need, and measuring from the curtain rod to the intended bottom edge. As a starting point, a 72 × 72 in curtain is a common residential reference size—not a guaranteed fit for commercial or vehicle installations. For custom orders, give your supplier the finished width and height, measurement units, opening details, and any required cutouts or special features.

At Huabao, our work in plastic profiles gives us a practical perspective on fit, dimensional details, and component specifications. This guide helps facility managers, hospitality buyers, RV manufacturers, and healthcare procurement teams prepare a clear sizing brief before requesting quotations.

Who This Guide Is For

This guide is intended for B2B buyers sourcing curtains for multiple rooms, units, or facilities. It is also useful when replacing an unusual size, specifying curtains for a new build, or comparing suppliers. Because installation layouts vary, treat the measurements below as planning guidance and confirm the final dimensions against the actual shower area.

How to Define a Custom Shower Curtain Size

A custom shower curtain size is the finished width and height needed to cover a particular shower opening. Width determines how much the curtain spans across the enclosure and whether it can overlap at the center or sides. Height is measured from the point where the curtain hangs to the desired lower edge, not simply from the floor to the ceiling.

Measure the Opening Before Ordering

1. Measure the usable opening width. Measure across the area the curtain must cover, following the rod or track if it curves. Record whether the measurement is taken inside or outside the enclosure.
2. Measure the drop. Measure vertically from the curtain’s hanging point to the desired bottom edge. A planning clearance of about 1–2 in above the floor or shower surface can help prevent dragging, but the right clearance depends on the layout and drainage.
3. Specify coverage and overlap. Note whether the curtain should meet, overlap, or wrap around the opening. For a two-panel or center-closing arrangement, describe the intended overlap rather than leaving the supplier to assume it.
4. Record installation details. Include rod or track type, hook or grommet arrangement, corner locations, obstructions, and any required slits or shaped edges.
5. Confirm units and tolerances. State inches or centimeters, and ask the supplier to confirm the finished-size tolerance and whether dimensions refer to the curtain panel or the covered opening.

For width planning, some buyers add coverage beyond the opening so the curtain can gather or overlap, but the amount depends on the installation and desired appearance. As a project-specific starting point, buyers may evaluate 6–12 in of additional coverage at the sides or closure area, then confirm the layout with a drawing or sample. Do not apply this allowance automatically to curved RV tracks or tight hospital spaces.

Size Considerations by Application

Hotels

Hotels often need consistent specifications across many bathrooms, but room layouts may differ by floor plan or renovation phase. Measure representative bathrooms and separate them into size groups instead of assuming every room uses one curtain size. For each group, specify finished width, drop, closure position, and the hanging system so replacement orders can match the installed setup.

Where a curtain must cover a bathtub or a wide shower, check the full rod path and how far the curtain needs to extend beyond the wet area. A straight measurement across the tub may not capture a curved rod or a recessed alcove. If repeatability matters, keep a dimensioned record for each room type and identify the measurement date or renovation version.

RVs and Other Recreational Vehicles

RV bathrooms are compact, and their shower pans, walls, and tracks can have nonstandard shapes. Measure along the actual curtain path, including any curve, rather than using the maximum wall-to-wall width as the finished panel width. Also check nearby fixtures and doors to make sure the curtain can open and close without catching.

For an RV order, provide a sketch or photos with measurements, and identify the track’s shape and attachment points. State whether the curtain needs a shaped lower edge or a cutout around an obstruction. Small fit differences can affect usable floor space, so confirm a first article or sample before approving a large production run when the design is unfamiliar.

Hospitals and Healthcare Facilities

Healthcare installations may require coverage that supports privacy while fitting a specific track and room layout. Confirm whether the curtain is used around a shower, bathing area, or another partition, since the required dimensions and hanging system may differ. Buyers should also check their facility’s applicable material, cleaning, fire-safety, and procurement requirements with the responsible internal team.

Specify the required panel width and drop, the number and position of attachment points, and any required openings or reinforced areas. Avoid assuming that a larger curtain automatically provides better coverage: excess material can interfere with access, cleaning, or nearby equipment. Have the intended users review a drawing or sample against the actual installation before standardizing the specification.

Materials and Construction Details to Specify

Size is only one part of a purchase specification. Ask suppliers which curtain material options they offer and confirm that the chosen option is suitable for the intended environment and care routine. Do not assume that a material is compatible with a particular cleaning chemical, temperature, or facility requirement unless the supplier can provide relevant product information.

Also define the top finish and hanging method, such as holes, grommets, or another attachment format, along with hem details and any reinforcement. These features can affect the usable drop and how the curtain sits when installed. If a project involves profiles or related plastic components, clarify their dimensions, material requirements, and interface with the curtain or track as separate line items.

Buyer Selection Framework

Common Sizing Mistakes

• Ordering by a familiar standard size alone: A standard reference may not match the actual opening or track.
• Measuring the room instead of the curtain path: Curves, recesses, and fixtures can change the required width.
• Leaving the bottom clearance undefined: Confirm whether the curtain should stop above the floor, meet a shower surface, or follow another requirement.
• Mixing panel size with opening size: State clearly which dimension is being quoted.
• Skipping a sample for unusual layouts: A preproduction review can reveal fit issues before a larger order proceeds.

Pricing, MOQ, and Lead-Time Questions

Custom dimensions can affect material usage, cutting, finishing, packaging, and production planning, so pricing depends on the full specification and order quantity. Minimum order quantities and lead times vary by supplier, product construction, and customization; request these details rather than relying on a general estimate. For a multi-site project, ask whether one specification can cover all locations or whether separate size groups are needed.

When requesting a quotation, send a size schedule, installation drawings or photos, quantity per size, material preferences, and destination. Ask the supplier to confirm the quoted finished dimensions, tolerance, sample process, packaging, and any assumptions they have made. For repeat orders, retain the approved specification and sample reference to reduce avoidable discrepancies.

Supplier Evaluation Checklist

• Can the supplier review drawings and identify missing measurements?
• Will the quotation distinguish finished panel dimensions from opening dimensions?
• Can the supplier explain available materials, top finishes, and customization options?
• Are sample approval, production timing, packaging, and order quantities stated clearly?
• Can the supplier support related components or profile requirements when they are part of the project?

Summary and Next Steps

The right custom shower curtain size is the size that matches the real installation—not a universal number. Measure the curtain path and drop, decide on coverage and bottom clearance, and document the rod or track, closure, attachment, material, and order quantities. Hotels should group comparable room layouts, RV buyers should measure the actual track and obstructions, and healthcare teams should confirm facility-specific requirements before approval.

Before placing a bulk order, prepare a dimensioned specification and request written confirmation of the finished size and any assumptions.
