Arctic hot tub parts and waterfall features

Arctic Spas hot tubs are built around a moulded acrylic shell with a cabinet, a pump set and a plumbing loop that feeds jets, air controls and water features. Over the years the hard-wearing structural parts tend to outlast the smaller fittings: it is the trim pieces, bezels, diverters and feature outlets that get handled, knocked, bleached by chemicals and faded by sunlight. Here we list replacement parts carrying the Arctic name, so that a single tired component can be swapped out instead of living with a feature that no longer looks or works the way it did.

What this range covers

The listing on this page is focused rather than broad, and is aimed at owners of Tundra series tubs who need a like-for-like feature part:

• Waterfall outlets — the black waterfall for Arctic Spas Tundra hot tubs, part number JET-103000, which forms the visible spout and trim where the feature water returns to the shell.
• Finish-matched trim — a black finish to suit shells and cabinets specified with dark hardware, so a single replacement does not stand out against the remaining fittings.
• Model-specific fitment — parts described for a named series rather than generic aftermarket spouts, which matters because feature cut-outs and rear connections differ between shells.

If a part you need is not shown, it is worth noting the number printed or moulded on the component itself, or the position number on the exploded view in the owner’s handbook, before searching further.

Where a waterfall sits in the plumbing

On most hot tubs a waterfall is not fed by the jet manifold directly. Water is usually taken from a dedicated line off the circulation or jet pump and sent to the feature through a diverter or an on/off valve on the topside, so the flow can be turned down when bathers want quiet, or opened fully for the visual effect. The outlet itself is mounted in a cut-out at the top of the shell, generally fixed from the front with a bezel or escutcheon and sealed against the acrylic, with the supply pipe connected behind.

That position explains the wear pattern. The spout is at eye level and gets leaned on, stood on during cover removal and cleaned repeatedly. Chlorine, bromine and UV exposure gradually make plastic trim brittle and dull, and once a lip or clip has snapped, water tends to run behind the fitting rather than over it.

Identifying the right part before ordering

Hot tub feature parts look similar in photographs but rarely interchange, so a few checks save a return:

• Confirm the model and series — Tundra parts are listed for that series; the model name is normally shown on the cabinet or on the data plate near the equipment bay.
• Match the part number — a number such as JET-103000 on the invoice, handbook or the old component is the most reliable identifier.
• Measure the old fitting — note the width and height of the visible trim and the diameter of the shell cut-out behind it before removing anything.
• Check the rear connection — see whether the supply arrives by glued pipe, barbed hose and clip, or a threaded union, and photograph it before disconnecting.
• Note the finish — black, grey and stainless-effect trims are not always available for every shell, so match what is already fitted.

Fitting and keeping it looking right

Work on a drained or part-drained tub so the water line sits below the feature. Keep the old gasket or seal until the new part is in place, so there is something to compare against; if the original seal is flattened, cracked or has taken a permanent set, replace it rather than reuse it. Hand-tighten plastic nuts and bezels and avoid tools where possible, as over-tightening is a common cause of hairline cracks in both the fitting and the surrounding acrylic.

Afterwards, rinse trim with clean water rather than household cleaners, and keep sanitiser levels balanced. Strongly over-chlorinated water and undissolved granules sitting against plastic are what shorten the life of visible fittings more than anything else.

Here you will find Arctic-branded replacement parts for hot tubs, listed by part number so the component can be matched to the model it was designed for rather than approximated. The emphasis is on the visible, serviceable items — feature outlets and trim — that owners most often need when a tub is otherwise sound.

Every item is listed with its manufacturer reference and the series it is described for, so you can cross-check against the old part or the exploded view in your handbook before ordering. If the number on your component does not appear here, send it through with the model name and we will look into what fits.
