What Do Built to Order, In Stock and Preorder Mean?

Updated September 2026

Built to order means every Ella walk-in tub is assembled, jetted and tested for a specific order in Chicago. Within that, in stock means the shell and components for your exact configuration are on hand so assembly can begin right away, and preorder (or backorder) means that configuration is scheduled for a later production run. None of the three words means a finished tub is sitting on a shelf; each tub still goes through assembly, leak testing, cleaning and crating before the freight carrier is booked.

How It Works

Tub shells are made in partner factories overseas, then shipped to Chicago, where each one is inspected on arrival, fitted with its jets and pumps, filled and leak-tested, checked at the door and latches, cleaned, crated and matched against its paperwork. Stock is tracked per model, door side, therapy package and color, not by model name alone, which is why a left-door soaker can be available while the right-door version of the same model is on preorder. A preorder records your configuration and holds your place in line for the next run. Once your tub ships, a shipment confirmation with a tracking number is emailed within 24 hours. The knowledge base publishes no production or delivery timeframes; timing depends on the model, options and current stock, and the team confirms it for your specific order. The complete explanation is in in stock, built to order and preorder.

Which Ella Models Have It

Every Ella walk-in tub is built to order, from the Petite to the two-seat tubs and the LayDown line; what varies is availability of a given configuration. Clearance and warehouse tubs are the exception in spirit: specific finished units sold as configured. For where the shells come from and how the Chicago steps go, see where Ella tubs are made and the build, test and pack video tour.

What to Know as an Owner

When you ask about availability, give the exact model, door side, therapy package, color and any accessories, and ask which combinations are on hand if your first choice is waiting on a run. Ordering while your configuration is available is the surest way to avoid a wait. If your bathroom will not be ready, say so when you order and ask whether shipment can be timed to your installer; the answer is agreed order by order, so ask rather than assume and tell the team as soon as your date moves. For a ticket about an order, have your order number, the configuration as written on your invoice and your installer's expected date ready. What happens between payment and delivery is laid out in order status: what happens next.

Common Questions

Does in stock mean my tub ships today?
No. In stock means the shell and components for your configuration are in the building so assembly can start right away. The tub is still assembled, jetted, tested, cleaned and crated before the carrier is booked, and you receive a tracking email within 24 hours of shipping.
What does preorder mean on a walk-in tub?
It means the shell or a component for that configuration is not in the building yet and your order will be built in a later production run. Your configuration is recorded and your place in line is held, and the team confirms timing once the run is scheduled.
Where are Ella walk-in tubs made?
Ella walk-in tub shells are made in partner factories overseas. Each tub is then shipped to Chicago, where it is assembled, jetted, and tested to order. Every tub is filled and leak-tested in Chicago before it is cleaned and crated for shipment.
Why is one door side in stock and the other on preorder?
Ella walk-in tub shells are stocked per door side, which means a left-door soaker can be available while the right-door version of the same model is on preorder. Therapy packages, colors, and accessories are also tracked separately. When you ask about availability, always give the exact model, door side, therapy package, color, and any accessories so the team can provide an accurate answer for your specific configuration.
Can shipment be held until my installer is ready?
You can ask if shipment can be held until your installer is ready when you place your order. Tell the team when your installer expects to be ready and whether the shipment can be timed to suit your schedule. The answer depends on the specific order and available space at the facility, so it is agreed upon case by case.
