referring now to fig1 , an opening 10 for use with a shower and storage unit 15 described herein is partially shown in a bathroom 20 . the bathroom has a floor 25 , a pair of front walls 30 , a pair of side walls 35 and a back wall 40 . the opening 10 is sized to fit a standard size tub ( not shown ), which may have shower equipment such as a shower head or a hand shower ( not shown ). the opening 10 usually has a width w of 60 inches and a depth d of 30 inches or more , i . e . the dimensions of a standard tub ( not shown ). the depth d is typically more than the 30 inches to allow a tub ( not shown ) to be recessed from front walls for decorative or other purposes . the depth d shown herein is 39 ″ inches though other depths are contemplated herein . a pan 45 having two sidewalls 50 and a back wall 55 and a bottom 60 is disposed on the floor 25 of the opening 10 . the pan has a zero threshold drain 65 . the zero threshold drain is flush with the floor 25 . such zero threshold drain is disclosed in the assignee &# 39 ; s patent application entitled bath system , ser . no . 12 / 533 , 046 , filed jul . 31 , 2009 , which is incorporated herein by reference . the zero threshold drain 65 allows a user to access the pan 45 without having to step over an edge ( not shown ) so that tripping is minimized the zero threshold drain 65 is typically as wide as the pan 45 and about 3 inches deep , though other depths are contemplated herein . referring now to fig2 , a shower left side wall 70 and a shower back wall 75 are installed against the left side wall 35 and back wall 40 of the opening 10 as is known in the art . the shower left side wall 70 and shower back side wall 75 are sealed against the left wall 50 of the pan 45 and the back wall 55 of the pan 45 respectively and against each other as is known in the art to minimize any leakage therefrom . a pair of grab bars 80 is installed against studs ( not shown ) or otherwise in the respective side wall and back wall as is known in the art . the shower left side wall 70 typically has a plurality of openings 85 for allowing plumbing fixtures such as a temperature and volume regulator and a stub out for a shower head ( not shown ) as is known in the art . next , a frame 90 , which may be prefabricated , is attached to the floor 25 of the opening 10 and the right side wall 35 in the opening 10 to provide support for the installed shower and storage unit 15 as will be described herein . the frame 90 has a pair of side portions 95 that are connected by welding or the like by a plurality of stiles 100 . each side portion has a vertical portion 105 , an upper portion 110 that cants slightly from horizontal and a shorter downwardly extending portion 115 . referring to fig2 a , the upper portion 110 may be split into a smaller section 110 b that telescopes into larger section 110 a so that the upper portion can fit by telescoping to attach to the right side wall 35 if irregular widths w ( see fig1 ) are encountered , e . g ., other than 60 inches . the frame is recessed from a front of the shower enclosure and storage unit 15 . as shown in fig2 b , bolts 120 are used to extend through holes 125 in a bottom stile 130 into the floor 25 . similarly as shown in fig2 c , bolts 135 are used to extend through holes 140 in stile 145 extending between downwardly extending portion 115 into the right side wall 35 . other securement means are also contemplated herein . referring now back to fig2 , a shower right side wall 150 is sealingly installed against the back wall 40 or the shower back wall 75 , the pan 45 and against the frame 90 . the attachment may be by glue , clips or screws or the like as is known in the art . the shower right side wall includes a hidden storage portion 155 that is designed to hold soap and shampoo or the like ( not shown ) in the shower enclosure . a space 160 is created between the shower right side wall 150 and the right side wall 35 . the space has a depth d ( see fig1 ) that is the same as the depth d ′ of the pan 45 and the width of the zero threshold drain though other depths are contemplated . as will be shown hereinbelow , the space 160 will be advantageously used . referring again to fig2 , a top portion 162 is secured to the upper portion 110 of the frame 90 . the top portion has a flange 165 depending downwardly therefrom that fits over the shower right side wall 150 . as stated above , the upper portion 110 is canted slightly from horizontal and the top portion 162 , which conforms to the upper portion so that if any is water splashed up on the top portion 162 , it will flow downwardly towards the shower enclosure , over the flange 165 and into the shower enclosure thereby minimizing any water flow outside the shower enclosure . the top portion 162 also provides a solid surface for additional storage . referring now to fig2 and 2d , a shower seat 170 is installed . the shower seat 170 has a bracket 175 that attaches conventionally to the bottom 180 of the shower seat 170 , to the shower right side wall 150 via faceplate 185 and through the shower right side wall 150 into the frame 90 . as can be seen in fig2 d , bolt 190 and a nut 195 are used to secure the shower seat 170 to the frame 90 via faceplate 185 and bracket 175 . referring now to fig3 - 7 , storage units 200 are shown that may be placed within the space 160 . the storage units 200 have a width that fits within the space and a depth that is generally just short of the width of a hidden storage unit 155 placed in the shower right side wall 150 . the hidden storage unit 155 will not interfere with objects that are placed in the opening that have a depth less than the width of the right side wall and the width of the hidden storage . referring specifically to fig3 , a storage unit 205 shows a floor 207 , two side walls 210 , molding 215 , back wall 220 and three shelves 225 that extend inwardly and outwardly on guides 230 . the storage unit may also have a door 235 to maintain a neat appearance . the storage unit may be mounted on casters 240 so that the storage unit 205 may be slid easily into and out of the space 160 if a different storage unit is desired . the door 235 may show decor that matches the room &# 39 ; s design . referring to fig4 , another storage unit 245 is shown . the storage unit has an upper drawer 250 and a lower drawer 255 . the upper drawer a front wall 260 , a back wall 265 and a pair of shelves 270 extending from the front wall to the back wall thereof . a set of partitions 275 prevent items from falling off the shelves . the upper shelf is mounted on guides ( see 230 in fig3 ). the lower drawer 255 is a sliding box that can function as a laundry basket or the like . this storage unit 245 has a solid right side wall 277 if the storage unit is installed where there is not a side wall 35 . in this case , the stile 145 attaches directly to the solid right side wall 277 . referring to fig5 , a shower door 280 , which may be a double panel 285 or a single panel ( see fig6 ), may be installed on the shower left side wall 35 and the shower right side wall 150 as is known in the art . however , other styles of shower doors are also contemplated herein . the storage unit 290 has a pair of sides 295 having molded slides 300 to hold shelves 305 . a sliding bench 310 having a comfortable seat 315 fits under the bottom shelf 307 within the storage unit 290 . the bench may have a hidden storage area 320 under the seat 315 . referring to fig6 , another storage unit 325 is shown having a fixed top shelf 330 , a lower drawer 335 mounted on casters 340 , and a slidable drawer 350 having four storage areas 355 extending along a length of the drawer 350 , two on either side thereof , separated by partition 360 and another open storage area 365 having a shelf 370 on the front 375 thereof . referring finally to fig7 , another embodiment of a storage unit 380 is shown having three fixed shelves 385 and a laundry hamper 390 mounted on casters 395 . although a combination of features is shown in the illustrated examples , not all of them need to be combined to
