Block Party 19' Dual Lane Water Slide with Attached Deep Pool

About the Block Party 19' Dual Lane

This is the largest slide in our catalog and the one that changes what an event looks like. Nineteen feet of dual-lane drop into an attached deep pool, in the bright primary Block Party colorway. At this scale the slide stops being a backyard toy and becomes the centerpiece of a fairground, a school field day, or a commercial rental fleet's headline unit — the one photographed for the booking page.

Nineteen feet is a meaningful threshold rather than an incremental step up from 17. The drop is long enough that riders reach genuine speed, which is why this unit uses a deep pool rather than a shallow splash basin: the extra water depth is what decelerates a rider arriving that fast. That deep pool is also why this slide demands more supervision than anything else here. It is not a unit to set up and glance at occasionally.

Dual lanes at this height serve throughput at scale. A 19-foot single lane cycles slowly because the climb is long; two lanes roughly halve the effective wait, which is the difference between a manageable queue and a hundred restless kids at a school event. If you are buying for volume, the height and the lane count have to move together or the unit becomes a bottleneck.

Space is the real constraint. You need substantial clear length, substantial width, and — critically — nineteen-plus feet of unobstructed overhead. That last requirement rules out a large share of residential yards regardless of ground area, because of tree canopy and service drops. Check the sky before you check the lawn.

Power is the second consideration. Larger units need more air, and this one is specified for two blowers rather than one. Two blowers means two circuits — not two outlets on the same circuit, which is the single most common setup failure on flagship units. Our blower guide covers how to work out what you actually need before delivery day rather than on it.
