A bubble tube standing on a hard floor is functional. A bubble tube set into a padded, mirrored square podium is a sensory room installation. The TFH Square Podium Base holds any TFH bubble or hurricane tube securely through a dedicated hole in the top, provides a padded vinyl seating surface directly beside the column, and lines the sides with mirrored acrylic that reflects the tube's colour and light outward into the room. Available across North America from The Sensory Supply at $1,295 CAD in four hole-size variants, it is the flat-wall and freestanding installation equivalent of the TFH corner podium — same dimensions, same construction, same part of the TFH Modular Sensory Room System, square format for placement against a flat wall, in the centre of a room, or as a freestanding unit.

The base is 36" x 36" x 15" — a generous square footprint that fits against most flat walls without projecting significantly into the room. The padded vinyl lid is white as standard, which reflects the tube's colour light for enhanced visual sensory stimulation around the user. The lid lifts off easily to access the tube base, power connections, and components inside for maintenance and water changes. The mirrored acrylic sides multiply the bubble tube's light and colour into the surrounding space, making the installation appear larger and more immersive than the tube alone. Holes for cables, wires, and other components pass cleanly through the base. Fibre optic tails can be routed through the podium and emerge from the surface to add a tactile sensory element to the seating experience.

Due to its weight and size, this podium ships via truck. Bubble tube, colour controller, and wall mirrors are not included.

Choosing the Right Hole Size

The hole in the top of the Square Podium Base accepts the base of the bubble or hurricane tube, holding it securely in position. Matching the hole size to your tube diameter is critical for a stable installation.

• No Hole: For display configurations where the tube rests on top of the podium surface, or for waterless hurricane tubes that sit on the surface rather than through it
• 4" Hole: For TFH Basic bubble tubes (4" diameter)
• 6" Hole: For TFH Standard (6" diameter) bubble tubes including the Interactive LED, Genie System, Frosted, and Wireless variants
• 8" Hole: For the TFH Giant Water Bubble Tube (8" Wide)

If you are unsure which diameter your tube requires, contact The Sensory Supply before ordering — hole size cannot be changed after manufacture.

Key Features of the TFH Square Podium Base

• Four Hole-Size Variants for All TFH Tube Diameters - Available in No Hole, 4" Hole (Basic tubes), 6" Hole (Standard, Genie, Interactive LED, Frosted, Wireless tubes), and 8" Hole (Giant 8" Wide tubes); select the variant that matches your tube diameter at the time of ordering
• Mirrored Acrylic Sides for Visual Enhancement - The sides of the podium are lined with mirrored acrylic that reflects and multiplies the colour and light from the bubble tube into the surrounding room, extending the visual sensory environment beyond the tube's immediate footprint
• White Padded Vinyl Lid - The cushioned top provides a comfortable, wipe-clean seating surface directly beside the tube; users can sit close to the column, place hands against the acrylic, and engage with the visual display at close range; the white colour reflects the tube's light for enhanced visual stimulation
• Lid Lifts Off for Component Access - The padded top lifts off easily to access the tube base, power connections, and water maintenance components inside for regular cleaning and water changes
• Sturdy Wood Construction with Component Routing - Sturdy wooden base with holes for cables, wires, and other components to pass through cleanly; provides a stable, professional installation platform suitable for daily institutional use
• Fibre Optic Routing Capability - The podium base provides a natural routing point for TFH fibre optic tails to emerge from the surface, adding a tactile and visual dimension to the seated sensory experience alongside the bubble tube
• 36" x 36" x 15" Square Format - The square format suits flat-wall placement, centre-of-room freestanding installations, and any configuration where a corner base is not required; the same 36" x 36" footprint as the TFH corner podium but in a straight square
• Part of the TFH Modular Sensory Room System - This podium works within TFH's modular furniture range — alongside corner seat bases, quadrant benches, and waterbeds — allowing sensory rooms to be configured and expanded over time
• Ships via Truck - Due to its weight and size, this item ships via truck freight; please account for truck delivery logistics when ordering

Square vs Corner - Choosing Your Podium Format

The TFH Square Podium Base and the TFH Corner Seat Base are identical in construction, pricing, and hole-size variant options. The difference is format. The Corner Seat Base is L-shaped to fit flush into a room corner, transforming the corner into the sensory installation anchor point. The Square Podium Base is a straight 36" x 36" square suited to placement against a flat wall or as a freestanding unit in the centre or along the side of a sensory room. Both are part of the same modular system and can be used together in a larger sensory room configuration.

For buyers planning a full sensory room with multiple tube installations, the two formats can be combined — corner base in the corner, square bases along the walls — to create a continuous modular seating and tube installation layout.

Ideal For

• Sensory rooms where a flat-wall or freestanding bubble tube installation is preferred over a corner format
• Occupational therapy clinics positioning a bubble tube along a wall or in the centre of a treatment space
• Schools and care facilities building modular sensory room configurations using TFH's Modular Sensory Room System
• Any setting where the corner podium's L-shape is not suitable for the room layout

• Dimensions: 36" L x 36" W x 15" H
• Construction: Sturdy wood base, mirrored acrylic sides, white foam/vinyl cushion lid (other colours available on request)
• Compatibility: All TFH bubble and hurricane tubes (4", 6", 8" diameter variants)
