Glass Door and Screen Options Beyond the 4-Fold: Sliding Doors, the Tidy Screen, the LayDown Bi-Fold and the Primo Door

Updated September 2026

The four-fold tempered glass screen is the best-known way to close in an Ella walk-in tub for showering, but it is not the only glass door and screen option Ella's Bubbles publishes. Depending on the tub and the opening, there is also the Duo framed sliding door, framed thick-glass sliders such as the Primo in 48 and 60 inch widths, the Tidy two-panel bath screen, and the bi-fold screen made for the LayDown tubs. This article lists each option with its published size so you can match it to your opening, and notes where the team should confirm fit before you order.

Published Glass Options and Sizes

  • Four-fold shower screen: 44 inches wide by 42 inches high. 1/8 inch tempered clear glass in an ionized aluminum chrome frame with PVC geared hinges, a rubber gasket angled inward to hold water in, reversible left or right installation, a 90 degree pivot for entry and a doorknob usable from either side. One panel can be removed to make a three-fold screen 32 inches wide by 42 inches high, which is how a 52 inch tub in a 60 inch alcove is handled. Available finish: chrome. The install is in installing glass shower screens.
  • Duo 55 by 70 framed sliding door. A two-panel clear tempered glass sliding door in a chrome frame; the drawing measures 55 1/4 inches wide by 71 inches high. Both panels slide for a choice of entry side, the extended horizontal handle doubles as a towel bar, it is reversible for left or right opening, and it carries a 2 year limited warranty. Ella's Bubbles lists it for its 60 inch wide one-piece and three-piece shower stalls.
  • Framed thick-glass sliding doors: 48 by 78 and 60 by 78 inches. The installation manual for these sliders gives the wall-to-wall adjustment as 46.02 to 48 inches for the 48 inch door and 58.03 to 60 inches for the 60 inch door, both 78 inches high, supplied without a tray. The Primo chrome sliding door and the Tidy sliding door appear on the site in these sizes, and a standard-glass Primo is listed at 60 by 72 inches.
  • Tidy two-panel bath screen: 55 by 39 inches. A tub-deck screen with a wall adjustment of 38.19 to 39 inches, supplied without a tray. A Tidy frameless bi-fold tub door in black is also listed on the site.
  • LayDown bi-fold glass shower screen. Listed as an optional feature on the LayDown spec sheets and shown on both LayDown product pages, which note that the bi-fold screen in the photos is optional and not included. With the screen installed, the drawings show a span of 38 1/4 inches on the LayDown60 and 44 1/2 inches on the LayDown72 at a height of about 57 inches.

This visual shows the Primo chrome tempered glass sliding door for walk-in bathtubs: two glass panels in a chrome frame sliding past each other on a top track. The site lists the Primo in a standard-glass version and a thicker-glass version, with sizes of 48 by 78, 60 by 78 and 60 by 72 inches across the listings. Because the framed slider installation manual is the only published dimension document, share your exact opening with the team so they can confirm which Primo fits.
This visual shows a frameless bi-fold glass door folding back on itself against the wall to open the tub deck, then closing to seal along the deck. It is the style used on the LayDown tubs, and the LayDown drawings above give the installed span for each size. Day-to-day use of that door is covered in operating and caring for the LayDown glass door.

Which Sliding Door Fits a 60 Inch Opening

For a 60 inch alcove, the published choices are the 60 by 78 inch framed thick-glass slider, whose adjustment range runs from 58.03 to 60 inches, the 60 by 72 inch standard-glass Primo, and the Duo 55 by 70, which Ella's Bubbles lists for its 60 inch shower stalls. For a walk-in tub rather than a shower stall, the four-fold screen remains the option designed for the tub deck, converting to three panels for a 52 inch tub with an extension panel (see extension panels and filler kits). If your opening is wider or narrower than these ranges, share the measurement with your Ella dealer or the team at (800) 480-6850 so they can confirm which door is right before you order.

Finishes

The Tidy frameless bi-fold tub door is the glass option listed in black.

The four-fold screen lists chrome as its available finish, the Duo has a chrome frame, and the Primo is named as a chrome door. The Tidy frameless bi-fold tub door is the one glass option listed in black. Product imagery on the site also shows Primo, Duo and Tidy doors in brushed nickel and matte black, so if a finish matters for your bathroom, confirm current availability with the team when you order.

Wall Requirements and Installation Notes

  • The wall plugs included with the Tidy and the framed sliders are for solid walls only; a stud or partition wall needs specialized fixings purchased separately.
  • Do not fix a wall profile to newly plastered, painted or papered walls; a chemical reaction may discolor the finish.
  • Check for hidden pipes and cables before drilling, and use masking tape on tile to keep the drill from wandering.
  • These products are heavy; two people are required to lift and install them.
  • Level the four-fold screen and set its height so the bottom gasket seats on the tub deck; a screen that leaks at the bottom is almost always a height or leveling issue.
  • On the LayDown screen, align the fixed panel with the glass door rather than centering it on the tub side, keep the gasket pointing toward the tub, and wait 24 hours for the silicone to cure before use.
  • Clean glass and frames with warm soapy water and a soft cloth; avoid abrasive cleaners, alcohol and petroleum-based products. See cleaning the glass screen, stainless door and chrome.

Step-by-step instructions for the sliders and the Tidy screen are in installing framed sliding shower doors and the Tidy screen, and gaskets, panels and hardware are covered in replacement parts for glass screens and doors.

Common Questions

What glass door and screen options exist for a walk-in tub besides the 4-fold screen?
Beyond the four-fold screen, Ella's Bubbles publishes the Tidy two-panel bath screen, the Duo framed sliding door, framed thick-glass sliders such as the Primo in 48 and 60 inch widths, and the bi-fold glass screen made for the LayDown tubs. Each option has a published size, listed above, so you can match it to your opening. Share your exact opening with the team so they can confirm fit before you order.
What is the Primo sliding glass door?
The Primo is a chrome-framed tempered glass sliding door with two panels that bypass each other. The site lists it in a standard-glass version and a thicker-glass version, with sizes of 48 by 78, 60 by 78 and 60 by 72 inches across the listings. Because the framed slider installation manual is the only published dimension document, the team confirms which Primo fits your opening.
Which sliding door fits a 60 inch opening?
For a 60 inch alcove, the published choices are the 60 by 78 inch framed thick-glass slider, whose adjustment range runs from 58.03 to 60 inches, the 60 by 72 inch standard-glass Primo, and the Duo 55 by 70, which Ella's Bubbles lists for its 60 inch shower stalls. For a walk-in tub rather than a shower stall, the four-fold screen remains the option designed for the tub deck, converting to three panels for a 52 inch tub with an extension panel. If your opening falls outside these ranges, share the measurement with your Ella dealer or the team at (800) 480-6850.
What screen does the LayDown use?
The LayDown tubs use an optional bi-fold glass shower screen, listed on the LayDown spec sheets and shown on both product pages. With the screen installed, the drawings show a span of 38 1/4 inches on the LayDown60 and 44 1/2 inches on the LayDown72 at a height of about 57 inches. It is not included unless ordered, so add it to your order if you want it.
Which options are chrome only?
The four-fold screen lists chrome as its available finish, the Duo has a chrome frame, and the Primo is named as a chrome door. The Tidy frameless bi-fold tub door is the one glass option listed in black. Product imagery on the site also shows Primo, Duo and Tidy doors in brushed nickel and matte black, so confirm current availability with the team if a finish matters for your bathroom.
Can the 4-fold screen be ordered with five panels, or is there a full-length screen?
No. The screen is offered as the four-fold, 44 inches wide by 42 inches high, and one panel can be removed to make a three-fold screen 32 inches wide; there is no five-panel or full-length version. The LayDown bi-fold covers about two thirds of that tub's length.
Does the 4-fold screen fit tubs like the Ultimate or Monaco?
Yes. The four-fold screen mounts to the side wall next to the tub rather than to the tub itself, so it works with these models as long as the tub sits in a corner or alcove with a wall beside the deck. It can also be added after the tub is installed. Level the screen and set its height so the bottom gasket seats on the tub deck.
Which wall does the screen attach to?
The screen attaches to the side wall beside the tub deck, on the wall side away from any extension panel. The Big4Two can take a screen on both sides. Check for hidden pipes and cables before drilling, and remember that these products are heavy and need two people to lift and install.
